What is the density of sulphur dioxide `( SO_(2))` at STP -

Options

A. `2.86 gm//lit `
B. `1.76 gm//lit`
C. `1.86 gm//lit`
D. None of these

Answer

A

Explanation

The gram molecular weight of `SO_(2) = 64 gm//`mole
Since 1 mole of `SO_(2)` occupies a volume of 22.4 litres at S.T.P.
Density of `SO_(2) =( 64)/(22.4) =2.86 gm//lit`.
