The volume occupied by 1.58g of a gas at S.T.P is 500cm3 3 . What is the relative molecular mass of the gas? [ G.M.V at S.T.P = 22.4dm3 3 ]

The volume occupied by 1.58g of a gas at S.T.P is 500cm${}^3$. What is the relative molecular mass of the gas?  [ G.M.V at S.T.P = 22.4dm${}^3$ ]

Answer Details

500cm3 of the gas weighed 1.58
: 22400cm3 of the gas weight
[22400 X 1.58g] ÷ [ 500 ]
= 71
