I don't really know how to go about this, Please help
1. Calculate the number of moles of the gas. Calculate the volume the gas would occupy at 100.0 C and 15.0 atm.
10.8 g He
2. Given the volume of 54.0 C and 790 torr, calculate the number of moles and mass.
38.1 L CO

1. Use PV = nRT.
P = 15
V = ?
n = grams/molar mass = 10.8/4 = ?
R = 0.08206 L*atm/mol*L
T = 273 + 100 = ?
2 is the same type problem but turned around a little.
