The molar specific heats of an ideal gas...

The molar specific heats of an ideal gas at constant volume and constant pressure are respectively 4.98 and 6.96 cal `mol^(-1) K^(-1)`. If the molecular weight of the gas be 32, then calculate the root means square speed of the molecule of the gas at `120^@ C`. (1 cal = 4.2 J)
