Question

What pressure is exerted by 0.450 mol of a gas at 25 degrees Celsius if the gas is in a 0.50 L container?

Answer 1

`P=22atm`

Explanation:

Assuming that the gas is behaving ideally, then we can use the ideal gas law:

`PV=nRT`.

Therefore, `P=(nRT)/V=(0.450cancel(mol)xx0.0821(cancel(L)*atm)/(cancel(mol)*cancel(K))xx298cancel(K))/(0.50cancel(L))=22atm`
