For preparing $0.1 \mathrm{~N}$ solution of a compound from its impure sample (percentage purity of which is known) weight of the substance required will be
less than the theoretical weight.
more than the theoretical weight.
same as the theoretical weight.
None of these.
Solution
More than theoretical weight since impurity will not contribute.
