Explanation:
Let's start by writing the equation of reaction:
The equation is not balanced, so lets balance it:
First balance the number of H atoms on both sides and then O atoms and we need atomic and molecular weights:
- Atomic weight of H = 1 gram
- Atomic weight of O = 16 grams
So,
In the question we are given 2 grams of
By the equation, we have:
or,
