Question

Porque una solución acuosa 30g de sal en 80g de agua Que % de masa de sal contiene

Answer 1

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 \ \% = (Mass \ of \ salt)/(Mass \ of \ salt + Mass \ of \ water)\\\\Mass \ \% = (30)/(30 + 80 )* 100 \%\\\\Mass \ \% = 27.27\ \%`

Hence, this is the required solution.
