One mole of gas A exerts a pressure of 25 mm Hg. How many molecules of gas B are required to exert a pressure of 125 mm Hg in an identical container at the same temperature?

One mole of gas A exerts a pressure of 25 mm Hg. How many molecules of gas B are required to exert a pressure of 125 mm Hg in an identical container at the same temperature?

Answer

Moles of B required to exert 125 mm Hg = 125/25 * 1 = 5 mol Molecules of B corresponding to 5 mol = 5 * 6.022 x 10^23 = 3.0 x 10^24 molecules
