what volume will 5.00g of dinitrogen oxide gas occupy at 50.0 degrees celcious and 12.0 atmosphere

Answer 1

Dinitrogen oxide, N2O, is also called nitrous oxide. (There is another nitrogen oxide with two N atoms: N2O4, but that is called nitrogen tetroxide).
The N2O molecular mass is 14+14+16 = 44 g/mole

5g of N2O is n = 5/44 = 0.1136 moles

The ideal gas law

V = nRT/P,

can be used to compute the volume.

Here is another way: At STP, the volume would be 0.1136 x 22.4 = 2.545 liters

At your T and P, multiply 2.545 l by
(1/12)*(323/273) to get the volume in liters. I get 0.25 l

Answer 2
