Final answer:
To find the percent change in mass of the soaked potato slice, subtract the initial mass from the final mass, divide by the initial mass, and multiply by 100%. The calculation shows an approximate 50% increase in mass after soaking.
Step-by-step explanation:
To calculate the percent change in mass of the soaked potato slice, you can use the following formula:
Percent change = ((final mass - initial mass) / initial mass) x 100%
Applying the values from the question:
- Initial mass (before soaking) = 12.6 g
- Final mass (after soaking) = 18.9 g
Percent change = ((18.9 g - 12.6 g) / 12.6 g) x 100% = (6.3 g / 12.6 g) x 100% ≈ 50%
Therefore, the percent change in mass of the potato slice after soaking is approximately 50%.
