Explanation:
Detailed explanation-1: -If you have a mole of cl2, then you have 6.02 * 10^23 molecules of cl2. If you want to calculate for atoms however, you can see that each molecule has two atoms of cl.
Detailed explanation-2: -= 3.01 x 1023 / 6.022 x 1023 = 0.500 mol. = 0.500 x 6.941 = 3.47 g.
Detailed explanation-3: -6.022 × 10 23 22.4 = 0.27 × 10 23 particles. Hence, the number of molecules in 1 liter of any gas at S.T.P is 0.27 × 1023 molecules.
Detailed explanation-4: -Hence, 52 g of N2O5 contains least number of molecules.
