Question

How many atoms of h2s are contained in 0.40 mole of h2s?

Answer 1

Explanation:

2S ? 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
