Calculate the molar mass of a gas if 4.40g occupies at 3.50 L at 560mmHg and 41 degrees celsisus

Answer 1

PV = nRT and solve for n = mols.
Then mols = grams/molar mass. You have mols and grams, solve for molar mass. Remember K must be in kelvin and P must be in atm if you use R as 0.08206

Answer 2

Solution please im confused

Answer 3

pv=nRT
n=PV/RT
n=0,7368x3500/0,8206x314
n=10
Mr=4,40/10
=0,44
