The volume occupied by 1.58g of a gas at S.T.P is 500cm³. What is the relative molecular mass of the gas? [ G.M.V at S.T.P = 22.4dm³]
A. 28
B. 32
C. 44
D. 71
Correct Answer:
Option D = 71
Explanation
500cm³ of the gas weighed 1.58
: 22400cm³ of the gas weight
[22400 X 1.58g] ÷ [ 500 ]
= 71

![The volume occupied by 17g of H2S at s.t.p. is [H = 1.00, S = 32.0, Molar volume = 22.4 dm³] The volume occupied by 17g of H2S at s.t.p. is [H = 1.00, S = 32.0, Molar volume = 22.4 dm³]](https://erudites.ng/wp-content/plugins/contextual-related-posts/default.png)
