What is the mass of hydrogen peroxide in 1 L of 3M solution ?

Explanation

To find the mass of hydrogen peroxide (H₂O₂) in a 1 L solution of 3 M concentration, we can follow these steps:

### Step 1: Understand Molarity
Molarity (M) is defined as the number of moles of solute per liter of solution. A 3 M solution means there are 3 moles of hydrogen peroxide in 1 liter of solution.

### Step 2: Calculate the Molar Mass of Hydrogen Peroxide
The molar mass of H₂O₂ can be calculated by adding the atomic masses of its constituent elements:
- Hydrogen (H): 1 g/mol (2 atoms) → 2 g/mol
