Calculate the average atomic mass of hydrogen using the following data
Isotope % Natural abundance Molar mass
`.^(1)H 99.985 1`
`.^(2)H 0.015 2`

Explanation

To calculate the average atomic mass of hydrogen using the provided data, we will follow these steps:

### Step 1: Understand the Data
We have two isotopes of hydrogen:
- Isotope \( ^{1}H \) with a natural abundance of \( 99.985\% \) and a molar mass of \( 1 \, \text{u} \).
- Isotope \( ^{2}H \) with a natural abundance of \( 0.015\% \) and a molar mass of \( 2 \, \text{u} \).

### Step 2: Write the Formula
