Sweet potato cylinders were placed in different concentrations of salt solution for three hours.
Table 1 shows the experimental data collected for three sweet potato cylinders, A, B, and C.
| Sweet potato cylinder | Mass at the start in grams | Mass after three hours in grams | Change in mass in grams |
|---|---|---|---|
| A | 4.5 | 5.1 | +0.6 |
| B | 4.8 | 5.5 | +0.7 |
| C | 4.6 | 5.3 | +0.7 |
Calculate the percentage change in mass of sweet potato cylinder B.
Use the equation:
percentage change=change in massmass at the start×100 \text{percentage change} = \frac{\text{change in mass}}{\text{mass at the start}} \times 100 percentage change=mass at the startchange in mass×100Give your answer to 2 significant figures.
