Question

15g of common salt was dissolved in water. The solution was found to weigh 115g. Calculate the mass by mass percentage of common salt in the solution

Answer 1

Answer:

The mass percentage is 13.04%.

Answer 2

Answer:

The mass percentage is 13.43%.

Explanation:

Given:

Weight of solute or common salt = 15 g

Weight of the solution = 115 g

Solution:

Let's calculate the mass percentage of solution,

Mass percentage of salt in the solution= $\frac{mass \thickspace of\thickspace solute}{mass \thickspace of \thickspace solution}$ × 100

Now substitute all the given values,

$\frac{15}{115}$ × 100  = 13.43%

∴ The mass percentage of common salt in the solution is 13.43%
