A technician mixes two samples of ethanoic acid solution, A and B. The table shows information about the samples.
| Sample | Volume of ethanoic acid solution | Concentration of ethanoic acid solution |
|---|---|---|
| A | 24.0 cm3 | 0.200 mol/dm3 |
| B | 16.0 cm3 | 0.150 mol/dm3 |
The technician has 35.0 cm3 of potassium carbonate solution with a concentration of 0.100 mol/dm3.
The equation for the reaction is 2CH3COOH+K2CO3→2CH3COOK+H2O+CO22\text{CH}_3\text{COOH} + \text{K}_2\text{CO}_3 \rightarrow 2\text{CH}_3\text{COOK} + \text{H}_2\text{O} + \text{CO}_22CH3COOH+K2CO3→2CH3COOK+H2O+CO2.
Calculate the volume of potassium carbonate solution needed to react exactly with both samples of ethanoic acid, and state whether the technician has enough potassium carbonate solution.
