In a school laboratory, a student synthesised ethyl ethanoate by reacting ethanol with excess ethanoic acid.
ethanol+ethanoic acid→ethyl ethanoate+water \text{ethanol} + \text{ethanoic acid} \rightarrow \text{ethyl ethanoate} + \text{water} ethanol+ethanoic acid→ethyl ethanoate+waterThe student reacted 25.0 g of ethanol and purified the resulting ester.
The experimental data is shown in the table below:
| Parameter | Mass (g) |
|---|---|
| Mass of ethanol reacted | 25.0 |
| Mass of ethyl ethanoate obtained from the reaction | 31.2 |
| Theoretical mass of ethyl ethanoate formed | 47.8 |
State the meanings of the terms actual yield and theoretical yield.
