1L = 1000 mL Molarity (M) = moles of solute / L of solution

Calculate the moles of NaCl required to prepare 250 mL of 1.5 M aqueous solution.

Fill in the blanks for the following statements: the rms speed of the molecules in a sample of h2 gas at 300 k will be times larger than the rms speed of o2 molecules at the same temperature, and the ratio µrms (h2) / µrms (o2) with increasing temperature.
