Question

At what temperature will 0.005 mol of gas occupy 600 mL at a pressure of 750 mm Hg? (R=0.0821 L atm / K mol)

Answer 1

If I am not mistaken this question should solve using ideal gas law.

PV = nRT

Volume must be in liters and pressure must be in atm.

(0.987)(0.6) = (0.005)(0.0821)T

0.5922 = (0.0004105)T

T = 1442.63

The temperature will needed is 1442.63 K

I am not sure whether my answer is right. But you could take a look in it.
