Question
Estimate the number of electrons in $100 \mathrm{~g}$ of water. How much is the total negative charge on these electrons ?
Step 1
The molar mass of water is 18 g/mol. So, the number of moles (n) is given by the formula: \[ n = \frac{mass}{molar~mass} \] Substituting the given values, we get: \[ n = \frac{100~g}{18~g/mol} = 5.56~mol \] Show more…
