Estimate the number of electrons in 100 g water. How much is the total negative charge on these electrons?

Explanation

To solve the problem of estimating the number of electrons in 100 g of water and calculating the total negative charge on these electrons, we can follow these steps:

### Step 1: Determine the number of water molecules in 100 g of water.
Water has a molar mass of approximately 18 g/mol. Therefore, we can calculate the number of moles in 100 g of water.

\[ \text{Number of moles of water} = \frac{\text{mass of water}}{\text{molar mass of water}} = \frac{100 \text{ g}}{18 \text{ g/mol}} \approx 5.56 \text{ moles} \]
