A 5.00 L flask with mass of 463.873 g is filled with Ar gas to 3 atm pressure at 292 k. (19 celsius + 273) what is the mass of flask and gas?

2 answers

Use the gas law equation and solve for n (moles):

PV=nRT

Where

P=3 atm
V=5.00L
R= 0.0821 liter·atm/mol·K
T=292K
and
n=???

Solve for n:

n=PV/RT

n*39.95g/mol=mass of gas
