What is the mass of a mole of water containing 50% of heavy water `(D_(2)O)`?

Explanation

To find the mass of a mole of water containing 50% heavy water (D₂O) and 50% normal water (H₂O), we can follow these steps:

### Step 1: Understand the composition of the mixture
We are dealing with a total of 1 mole of water, which consists of:
- 0.5 moles of heavy water (D₂O)
- 0.5 moles of normal water (H₂O)

### Step 2: Calculate the molar mass of D₂O
