Question

22.5g of washing soda is dissolved in 180g of solution. Calculate percentage composition of solution.

Answer 1

The percentage composition of solution is 12.5 %.

Explanation : Given,

Mass of washing soda (solute) = 22.5 g

Mass of solution = 180 g

As we know that the percentage composition is the mass of solute divided by the mass of solution multiplied by 100.

Formula used:

$\text{Percentage composition}=\frac{\text{Mass of solute}}{\text{Mass of solution}}\times 100$

Now putting all the given values in this formula, we get:

$\text{Percentage composition}=\frac{22.5g}{180g}\times 100$

$\text{Percentage composition}=12.5\%$

Therefore, the percentage composition of solution is 12.5 %.
