Calculate the mass of the following
2.24 litre of `SO _(2)` gas at S.T.P.

Text Solution

Verified by Experts

Molecular mass of `SO _(2) = 32 + (16 xx 2) = 32 + 32 = 64`
Number of moles of `SO _(2) = (SO _(2) at S. T. P)/("Molar volume" SO_(2))` at S.T.P.
Number of moles of ` SO _(2)= (2.24)/(22.4) = 0.1 ` mole
Number of moles `=("Mass")/("Molecular mass")`
Mass = No. of moles `xx` molecular mass
Mass `=0.1 xx 64`
Mass of `SO _(2) = 6.4 g`
