What is the rms speed of an atom in a sample of He gasat 25 °C?

A 1.69 mol sample of He gas is confined in a 42.0 liter container at 29.5 °C. If 1.69 mol of Xe is substituted for the 1.69 mol of He, holding the volume and temperature constant, the average molecular speed will decrease remain the same not enough information to answer the question O increase
