A student carries out two separate reactions to make the same product. The results are shown in the table.
| Reaction | Maximum theoretical mass of product (g) | Mass of product collected (g) |
|---|---|---|
| 1 | 25.0 | 18.0 |
| 2 | 40.0 | 34.0 |
Calculate the percentage yield of the product from both reactions combined.
