Question

What is nass of hydrogen peroxide in 1L of 3M sol

Answer 1

Answer:

The mass of hydrogen peroxide in 1L of 3M solution is 102 grams.

Explanation:

Molarity: it is defined as the number of moles of solute present in one liter of volume of solution.

Formula used :

Molarity =moles of solute

Volume of solution in (L)

In this question, the solute is hydrogen peroxide (H2O2).

Now put all the given values in this formula, we get :

3M=moles of solute

1L

Moles of solute =1L×3M

Moles of solute =3 Moles.

The number of moles of hydrogen peroxide is 3 Moles.

Now we have to calculate the mass of hydrogen peroxide.

Mass of H2O2 =moles of H2O2 ×moles of H2O2

Molar mass of hydrogen peroxide =34g/mole.

Mass of H2O2 =3 Moles ×34g/mole=102g.

Therefore, the mass of hydrogen peroxide in 1L of 3M solution is 102 grams.
