What pressure, in atmospheres, will be exerted by 2,500g of oxygen gas (O2) when stored at 22°C in a 40.0 L?

Gases are sold in large cylinders for laboratory use. What pressure, in atmospheres, will be exerted by 2,500g of oxygen gas (O2) when stored at 22°C in a 40.0 L?

Thanks in advance to anyone that answers.

We can use the equation PV=nRT
which means that P=(nRT)/V

u can then subsitute what u know- P=(781.25mols * .0821 * 295K)/40L

P=473.037atm

my chem is somewhat rusty but i believe this is correct
