A gas jar contains 1.6 g of sulphur dioxide gas at S. T.P. calculate volume of gas at S. T.P. [S = 32, O = 16]

Text Solution

Verified by Experts

Molecular weight of `SO_(2)` = 32 + 32 = 64 a.m.u
`therefore` 1 mole of `SO_(2)`=1 G.M.W=64 g
1 mole of `SO_(2)` at S.T.P. occupies = `22400 cm^(3)`
`therefore0.025` moles of `SO_(2)` at S.T.P occupies
`=0.025xx22400cm^(3)`
`=560cm^(3)`
