Sloane · Answer 1

Mass of solution = 2 g

Explanation:

Given dа ta:

Mass of CuSO₄ = 0.20 g

Percent by mass = 10%

Mass of solution needed = ?

Solution:

Formula:

Percent by mass = mass of solute / mass of solution * 100

Now we will put the values.

10 = 0.20 g / mass of solution * 100

10 / 100 = 0.20 g / mass of solution

0.1 = 0.20 g / mass of solution

Mass of solution = 0.20 g / 0.1

Mass of solution = 2 g
