Calculate the density of oxygen,O2 , under each of the following conditions:
1 STP
2 1.00 atm and 35.0 C

DrBob222,
If its an ideal gas (which it isn't), the gas at STP will occupy 22.4 L/mol.
1 mol = 32 g for oxygen.
density = 32/22.4 = ??
For 308 K, determine how much 22.4 L will occupy from V1/T1 = V2/T2.
Then 32/V2 = ??
Check my thinking. Check my numbers.

Entedar,
For part 1, STP is 1.43 which is correct.
