How many moles of oxygen gas can be produced during electricity decomposition of 180 g of water ?

Options

A. 2.5 moles
B. 5 moles
C. 10 moles
D. 7 moles

Explanation

To solve the problem of how many moles of oxygen gas can be produced during the electrolytic decomposition of 180 g of water, we can follow these steps:

### Step 1: Write the balanced chemical equation for the decomposition of water.
The balanced equation for the electrolytic decomposition of water (H2O) is:
\[ 2 \text{H}_2\text{O} \rightarrow 2 \text{H}_2 + \text{O}_2 \]

### Step 2: Determine the molar mass of water.
The molar mass of water (H2O) can be calculated as follows:
