Question

Gas is contained in an 8.45 liter vessel at a temperature of 19.8oC and a pressure of 8.70 atm. Determine the number of moles of gas in the vessel. Do not enter units.
Use the ideal gas law.

n = P*V/(R*T)

R = 0.08206 liter*atm/(mole*K)
T = 293.0 K
P = 8.70 atm
V = 8.45 l

Solve for n, which will be in moles.

n = 3.06 (moles)
