Question

15g of common salt is dissolved in water . the solution was found to weigh 115g. calculate the mass % of the salt in the solution also calculate the amount of solvent

Answer 1

masspercent of salt = (15/115)*100 13.043%

Answer 2

Answer: The mass percentage is 13.43%.

From the given

Weight of common solvent = 15 g

Weight of the solution = 115 g

Solution:

Let's calculate the mass percentage of solution.

$Mass\quad percentage\quad of\quad solution\quad =\quad \frac { Mass\quad of\quad the\quad solvent }{ Mass\quad of\quad the\quad solution\quad  }\quad \times \quad 100$

Let's substitute all the given values.

$=\quad \frac { 15 }{ 115 } \times 100\quad =\quad 13.43$%
