Question

Use the ideal gas law equation to solve for moles. Once you have your moles, convert to grams by using the relationship between gram and moles from your periodic table.

No, I think it's best if you tried it yourself. I need to leave soon. But here is the formula:

PV = nRT
you're solving for "n"

P = pressure (in atm)
V = volume (in L)
n = moles 
R = gas constant
T = temperature (in K)

rearraange using algebra to solve for moles. Then use dimensional analysis to cancel units and find grams.
