Question

Calculate the concentration of 45g salt present in 500g of solution

Answer 1

45/500 multiply it by 100

= 45/5

=9%

Therefore solution is 9% concentrated.....

Answer 2

Given:

Mass of solute = 45g

Mass of solution = 500g

To find:

Concentration of the solution = ?

Formula to be used:

Mass % of a component = $\frac{Mass of the components in the solution}{Total mass of the solution} \times 100$

Calculation:

When the given values are substituted in the formula of it gives concentration of the solution which is as follows:

Mass % of a component = $\frac{Mass of the components in the solution}{Total mass of the solution} \times 100$

Mass % = $\frac{45g}{500g}\times 100$

Mass % = 0.09×100

Mass % = 9

Conclusion:

Thus the concentration of 45g salt present in 500g of solution is 9.
