Question

caculate mass of 2.5g molecules of h2s

Answer 1

molecular mass of H2S=2+32=34amu

gram molecular mass of H2S=34g

mass of 2.5g molecules of H2S=34x2.5=85g

Answer 2

Answer:

85 g molecule of h2s.

Explanation:

1g of molecular mass of h2s ≡ 34g molecules of h2s

∴2.5g of molecular mass of h2s ≡ 34 x 2.5 g molecule of h2s

                                                     = 85.
