An experiment was carried out to ferment glucose and produce ethanol. Table 1 shows the mass of glucose used and the actual and theoretical masses of ethanol of this reaction.
| Mass in g | |
|---|---|
| Mass of glucose | 160.00 |
| Mass of ethanol obtained | 14.76 |
| Theoretical mass of ethanol formed | 82.00 |
Use the information in Table 1 to calculate the percentage yield of ethanol in this experiment.
