Question

The concentration copper sulphate solution is 25%. What mass of copper sulphate would be required to make saturated solution in 150g of water at 290K?

Answer 1

Given:

 The concentration of copper sulphate solution is 25%.

To find:

Mass of copper sulphate required to make a saturated solution in 150g of water at 290K?

Step-by-step explanation:

The concentration of copper sulphate solution is 25%.

i.e. 25%. = $\frac{25}{100}*1000$ = 250g per kg

That means the remaining 75% is water.

∴ The mass of copper sulphate would be required to make saturated solution in 150g of water

= $\displaystyle \frac{150 * 250}{1000}$

= 37.5g

37.5g of copper sulphate would be required to make saturated solution in 150g of water at 290K.
