How many mole of glycerine should be added to 1 litre of 1 M `H_(3)BO_(3)` so that 80% of boric acid form boric acid-glycerine complex ?
`H_(3)BO_(3) +` Glycerine `rarr `Complex` Kc = 0.90`

Explanation

To solve the problem of how many moles of glycerine should be added to 1 liter of 1 M \( H_3BO_3 \) so that 80% of the boric acid forms a boric acid-glycerine complex, we can follow these steps:

### Step-by-Step Solution:

1. **Identify Initial Concentrations**:
- We have 1 liter of 1 M \( H_3BO_3 \), which means the initial concentration of boric acid is 1 M. Therefore, the initial number of moles of \( H_3BO_3 \) is:
\[
n_{H_3BO_3} = 1 \, \text{mol}
