A student investigated the effect of sodium chloride solution concentration on the water potential of sweet potato (Ipomoea batatas) cylinders.
For one sweet potato cylinder immersed in a high-concentration salt solution:
Calculate the percentage decrease in mass of this sweet potato cylinder.
Use the equation: percentage decrease in mass=decrease in massinitial mass×100\text{percentage decrease in mass} = \frac{\text{decrease in mass}}{\text{initial mass}} \times 100percentage decrease in mass=initial massdecrease in mass×100
