How many electrons are present in 1.6 g of methane?

Explanation

To determine the number of electrons present in 1.6 g of methane (CH₄), follow these steps:

### Step 1: Determine the molar mass of methane (CH₄)
- Carbon (C) has an atomic mass of 12 g/mol.
- Hydrogen (H) has an atomic mass of 1 g/mol.
- Methane (CH₄) consists of 1 carbon atom and 4 hydrogen atoms.

\[ \text{Molar mass of CH₄} = 12 \, \text{g/mol} + (4 \times 1 \, \text{g/mol}) = 12 \, \text{g/mol} + 4 \, \text{g/mol} = 16 \, \text{g/mol} \]
