Here is the approach
use the ideal gas law PV=nRT
Solve for the moles "n". You have the other components. Use the correct "R" for liters and mm Hg. Or, convert the torr to atm. and then you can use 0.082.
Once you have moles, use the grams given and solve for molecular mass. If it is a noble gas, the molecular mass will correspond directly to the elemet's molecular mass. Look it up on the Periodic Table. Otherwise, the gas is diatomic. If so, divide the solved molecular mass by 2 and get the mass of the atom. Fine it on the Periodic table

find it yourself you lazy asshole. You didn't even put a question mark at the end of the sentence.
