Problem
A 5.00 L steel cylinder contains dry nitrogen gas (N2, molar mass = 28.02 g mol−1) at a temperature of 298 K and a pressure of 2.50 atm. The gas behaves ideally.
(a) Calculate the rms speed of a nitrogen molecule in the cylinder at 298 K. Express your answer in m s−1 and use an appropriate number of significant figures.
(b) Convert the value obtained in part (a) to km h−1. Show your unit analysis clearly.
