First, you want to divide each of the percentages of the elements by their molar mass.
Carbon= 49.5 / 12.011 mol =4.121 moles of carbon
Hydrogen= 5.2 / 1.008 mol = 5.159 moles of hydrogen
Oxygen= 16.5/ 15.999 mol= 1.031 moles of oxygen
Nitrogen= 28.8/14.007 mol=2.056 moles of nitrogen

Next, divide each molar amount we just found by whichever amount is the smallest. In this case we will divide them all by the moles of oxygen.

Carbon=4.121 (mol/C0)/ 1.031 (mol/O) = 4 mol C/ mol O
Hydrogen-5.159 (mole/H) / 1.031 (mol/O)= 5 mol H/ mol O
Oxygen = 1.031 (mol/ O) / 1.031 (mol/O) = 1 Mol O/ mol O
Nitrogen= 2.056 (mol/N) / 1.031 (mol/O)= 2 mole N/ mol O

By rounding them to the nearest whole number we will get our empirical formula: C4H5N2O …show more content…
Carbon= 194.2 x 0.4948= 96.0852
Hydrogen= 194.19 x 0.0519 = 10.07846
Oxygen= 194.19 x 0.1648 = 32.0025
Nitrogen= 194.19 x 0.2885 = 56.0238

Divide the number we just found for each element by its atomic weight.

Carbon= 96.0852 ÷ 12.011 = 7.9997
Hydrogen= 10.07846 ÷ 1.008 = 9.998
Oxygen= 32.0025 ÷ 15.9994 = 2.000
Nitrogen= 56.0238 ÷ 14.0067 = 3.9997 Round each answer to the nearest whole number and we will get our molecular formula of = C8H10N4O2

An empirical formula gives the lowest whole number of atoms in a compound. Molecular formulas are actual formulas of

The Wall Street Journal Case in the News

...Opticia Miami Dade College Opticianry An Optician is a vision expert; a health professional specially trained to supply, prepare, and dispense optical appliances through interpretation of written prescriptions. An Optician is an integral part of the vision care experience that adheres to exacting standards in order to enhance your vision. In this field, the optician responsibilities are finishing and fitting eyeglass lenses, frames, and contact lenses. An Optician turn the Doctor’s prescription into the glasses or contact lenses the patient or customer need to make their vision the best it can be. An optician can also dispense low vision aids and artificial eyes. Education and Training Requirement Becoming an optician, most opticians have at least a high school diploma. Opticians typically learn job skills through formal on-the-job programs. This training includes technical instruction in which, for example, new opticians measure a customer’s eyes or adjust frames under the supervision of an experienced optician. Trainees also learn sales and office management practices. A number of community colleges and technical schools offer formal education in opticianry. Some award an associate’s degree, which takes two years. Others offer a certificate, which takes one year. As of 2010, the Commission on Opticianry Accreditation accredited twenty one associate's degree programs in fourteen states. Miami Dade College is one of the institution that offers the Opticianry...

Evolution of Computer

...Background of the study The computer as we know it today had its beginning with a 19th century English mathematics professor name Charles Babbage. He designed the Analytical Engine and it was this design that the basic framework of the computers of today are based on. Generally speaking, computers can be classified into three generations. Each generation lasted for a certain period of time,and each gave us either a new and improved computer or an improvement to the existing computer. First generation: 1937 – 1946 - In 1937 the first electronic digital computer was built by Dr. John V. Atanasoff and Clifford Berry. It was called the Atanasoff-Berry Computer (ABC). In 1943 an electronic computer name the Colossus was built for the military. Other developments continued until in 1946 the first general– purpose digital computer, the Electronic Numerical Integrator and Computer (ENIAC) was built. It is said that this computer weighed 30 tons, and had 18,000 vacuum tubes which was used for processing. When this computer was turned on for the first time lights dim in sections of Philadelphia. Computers of this generation could only perform single task, and they had no operating system. Second generation: 1947 – 1962 - This generation of computers used transistors instead of vacuum tubes which were more reliable. In 1951 the first computer for commercial use was introduced to the public; the Universal Automatic Computer (UNIVAC 1). In 1953 the International Business Machine (IBM)...

Computer

...Computer From Wikipedia, the free encyclopedia Jump to: navigation, search For other uses, see Computer (disambiguation). "Computer technology" redirects here. For the company, see Computer Technology Limited. A computer is a programmable machine designed to sequentially and automatically carry out a sequence of arithmetic or logical operations. The particular sequence of operations can be changed readily, allowing the computer to solve more than one kind of problem. Conventionally a computer consists of some form of memory for data storage, at least one element that carries out arithmetic and logic operations, and a sequencing and control element that can change the order of operations based on the information that is stored. Peripheral devices allow information to be entered from external source, and allow the results of operations to be sent out. A computer's processing unit executes series of instructions that make it read, manipulate and then store data. Conditional instructions change the sequence of instructions as a function of the current state of the machine or its environment. The first electronic computers were developed in the mid-20th century (1940–1945). Originally, they were the size of a large room, consuming as much power as several hundred modern personal computers (PCs).[1] Modern computers based on integrated circuits are millions to billions of times more capable than the early machines, and occupy a fraction of the space.[2] Simple computers...
