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

Explanation

To estimate the number of electrons in 100 g of water and calculate the total negative charge on these electrons, we can follow these steps:

### Step 1: Determine the mass of water
We are given the mass of water as 100 grams.

### Step 2: Find the molar mass of water
The molecular formula of water is H₂O. The molar mass of water can be calculated as follows:
- Hydrogen (H) has a molar mass of approximately 1 g/mol, and there are 2 hydrogen atoms in water.
