Here's the solution for the next problem. Problem 1(a): Given: Volume of hydrogen gas = 12 dm^3 at r.t.p. Step 1: Calculate the number of moles of hydrogen gas. At room temperature and pressure (r.t.p.), the molar volume of any gas is 24 dm^3/mol. Moles = VolumeMolar Volume Moles of H_2 = 12 dm^324 dm^3/mol = 0.5 mol Step 2: Calculate the number of molecules of hydrogen gas. Avogadro's number (N_A) is 6.022 × 10^23 molecules/mol. Number of molecules = Moles × N_A Number of molecules of H_2 = 0.5 mol × 6.022 × 10^23 molecules/mol = 3.011 × 10^23 molecules The number of moles of hydrogen gas is 0.5 mol and the number of molecules is 3.011 × 10^23 molecules. That's 2 down. 3 left today — send the next one.
