Question

How many grams of hydrogen sulphide contains one half as many molecules of H2S as there are in 11.2 grams of nitrogen gas?
​

Answer 1

Answer:

1mole = 1 gram atom. Therefore, 0.40 mole of H2S contains 2 x 0.40 = 0.80 gram atoms of H and 0.40 gram atoms of S.

Explanation:

1mole = 1 gram atom. Therefore, 0.40 mole of H2S contains 2 x 0.40 = 0.80 gram atoms of H and 0.40 gram atoms of S.
