Question

Calculate molarity of 5%w/v CUSO4.2H2S​

Answer 1

Answer:

do by hint

Explanation:

30% W/V H2O2 means that for each 100 mL of solution there are 30 g of hydrogen peroxide.

The molarity is obtained as moles of solute in 1 L (1000 mL) of solution.

In your case, 1 L of solution contains 300 g of H2O2 (PM=34.01 g/mol).

Therefore, the molarity is (300 g/34.01 g/mol) = 8.82 M.
