#density = 1.95 g/L#

Use these 2 formulas:

#PV = nRT#

#mols = g/(mm)#

Note: mm is molar mass

Combine them to get:

#PV = g/(mm)RT#

Since you are trying to solve for g/L, rearrange the formula:

#g/V = (P*mm)/(RT)#

#g/V = ((3.00atm)*(16.04g/(mol)))/((0.08206(L*atm)/(K*mol))(301K))#

#g/V = 1.948173405#

Since you only have 3 sig figs, the answer would be:

#density = 1.95 g/L#
