Question

A gas sample has an initial volume of 4.5 liters at a pressure of 731 mmHg. If the volume is increased to 8.9 liters, what is the pressure?
p1v1 = p2v2
What is the volume occupied by 12.3 g or argon gas at a pressure of 1.17 atm and a temperature of 455K?
Use PV = nRT.
n = grams/molar mass
That is the ideal gas law
Pv=nRT
Use the Given/the known and you will get the answer
Given:
known RPT 0.08206 atm x L/mol x K
