Calculate the pressure in an evacuated 250. mL container at 0.00 degrees C if 3.20 cm^3 of liquid oxygen evaporates. Assume that the liquid oxygen has a density of 1.118 g/cm^3

I understand that the density and volume can be used to find the mass in grams. However, I'm confused about how the 3.20 cm^3 of oxygen that evaporates translates into the problem. Thanks in advance!

• Chemistry -

1.118 g/cc x 3.20 cc = ?grams O2.
?grams O2/molar mass O2 = n O2.
Then use n in PV = nRT and solve for P.
