WebProblem #13:Calculate the volume 3.00 moles of a gas will occupy at 24.0 °C and 762.4 mm Hg. Solution: Rearrange the Ideal Gas Law to this: V = nRT / P Substitute values into the equation: V = [(3.00 mol) (0.08206 L atm mol¯1K¯1) (297.0 K)] / (762.4 mmHg / 760.0 mmHg atm¯1) Note the conversion from mmHg to atm in the denominator.
