Question

Determine the molar mass of H2O2 (the solute) in a 1.5M aqueous solution of H2O2

Answer 1

The molar mass of H₂O₂ (the solute) in the aqueous solution of

H₂O₂ is 51 g

Step-by-step explanation:

Given;

H₂O₂ compound

Concentration of aqueous solution of H₂O₂ = 1.5M

The molecular mass of H₂O₂ = (1 x 2) + (16 x 2) = 34 g/mol

`Concentration(M) = (Reacting \ mass \ (g))/(Molar \ mass \ (g/m))`

Reacting mass (g) = Concentration x Molar mass

Reacting mass (g) = 1.5 x 34

Reacting mass (g) = 51 g

Therefore, the molar mass of H₂O₂ (the solute) in the aqueous solution of

H₂O₂ is 51 g
