Question

A sample of oxygen gas (O2) applies 152 mmHg pressure on the walls of an 11.2 L steel container at 273 K. Assume ideal gas behavior. The ideal gas constant is 62.36 (L·mmHg)/(K·mol), and the molar mass of oxygen gas is 32 g/mol.
How many grams of oxygen gas are in the steel container?
(I've tried to solve it but i cant figure the right equation.)

A: 1.6g
B: 32 g
C: 3.2g
D: 16g

Answer 1

Btw, just did exam, and its definitely not 1.6 g.

Answer 2

So you've tried it and didn't get the right answer. So why didn't you show your work and save us some time. We could spot the error in no time.
Use PV = nRT. Solve for n = PV/RT
n = number of mols = 152 mm*11.2L/63.36*273
n = 0.1
Then mols x molar mass = grams = 0.1 x 32 = ? g
