80 g of `H_(2)` is reacted with 80 g of `O_(2)` to form water. Find out the mass of water obtained. Which substance is the limiting reagent ?

Explanation

To solve the problem, we need to follow a systematic approach:

### Step 1: Write the balanced chemical equation
The reaction between hydrogen and oxygen to form water can be represented as:
\[ 2H_2 + O_2 \rightarrow 2H_2O \]

### Step 2: Calculate the number of moles of each reactant
To find the number of moles, we use the formula:
