Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".

An organic chemist isolates a colorless liquid from a petroleum sample. She places the liquid in a pre-weighed flask and puts the flask in boiling water, which vaporizes the liquid and fills the flask with gas. She closes the flask and reweighs it. She obtains the following data: Volume (V) of flask = 196 ml T = 99.1°C P= 751 mmHg mass of flask + gas = 81.5 g mass of flask = 78.3 g Calculate the molar mass (in g/mol) of the liquid.

The noble gas argon was discovered by Sir Walter Ramsay and John William Strutt in England in 1895. Through this discovery, they made highly accurate measurements of gas densities. Their experimentally determined densities are: Oxygen 1.42952 g/L Nitrogen 1.25718 g/L Air 1.29327 g/L 1) To determine the density of atmospheric nitrogen, Strutt removed the oxygen, water, carbon dioxide, and argon from air and then filled an evacuated glass tube with the remaining gas. He determined that a mass of 0.20389 g of nitrogen has a density of 1.25718 g/L under standard conditions of temperature and pressure. What is the volume of the glass tube in cm3?
