I find difficulty in solving this question: How many atoms of H & S are contained in 0.40 mole of H2S?

Expert Answer:

H2S ? 2H + S
 1 mole H2S  contains = 2 moles of H or 2 X 6.023 x 10 23 atoms .
 .4 mol contains = .4 x 2 x 6.023 x 10 23 atoms.
Similarly, 1 mole H2S contains = 1 mole of S = 6.023 X 10 23
              .4 mol H2S contains = .4 x 6.023 x 10 23atoms
