    Given :

    An aqueous solution of 30g of salt in 80g of water.

    To Find :

    The % mass of the salt.

    Solution :

    Mass percentage of the salt is given by :

    Mass \ \% = \dfrac{Mass \ of \ salt}{Mass \ of \ salt + Mass \ of \ water}\\\\Mass \ \% = \dfrac{30}{30 + 80 }\times 100 \%\\\\Mass \ \% = 27.27\ \%

    Hence, this is the required solution.
