Question
During an osmosis experiment to determine the movement of water, students are attempting to determine the percent change in the mass of a carrot after it has been placed in a solution with sucrose for 24 hours.Fresh Chopped Carrot by ivabalk (CC0)If the starting mass of the carrot was 3.2 grams3.2 grams and the ending mass was 2.6 grams2.6 grams, what was the percent change in mass?Elimination ToolSelect one answerA−23.1%−23.1%B19%19%C−18.75%−18.75%D−0.1875%
Solution
To calculate the percent change in mass, you can use the following formula:
Percent Change = [(Final Value - Initial Value) / Initial Value] * 100
In this case, the initial value is the starting mass of the carrot (3.2 grams) and the final value is the ending mass of the carrot (2.6 grams).
So, the calculation would be:
Percent Change = [(2.6 - 3.2) / 3.2] * 100
This gives us:
Percent Change = [-0.6 / 3.2] * 100
Which simplifies to:
Percent Change = -18.75%
So, the percent change in the mass of the carrot after being placed in the sucrose solution for 24 hours is -18.75%. This means the carrot lost 18.75% of its mass. Therefore, the correct answer is C−18.75%.

An experiment was conducted to determine how quickly water would move from one area to another through the process of osmosis.Six different concentrations of sucrose were placed in identical containers, with the same volume of solution in each. The containers allowed water to pass through, but nothing else. Containers were placed in equal volumes of water. The containers sat in the solution for 30 minutes. The initial and final masses of the containers were taken, and a percent change in mass was calculated to determine how much water entered the tubing during the 30-minute time period.What is the independent, dependent, and control variable in the experiment?Elimination ToolSelect one answerAIndependent Variable Dependent Variable ControlPercent Change in Mass Concentrations of Sucrose ContainersBIndependent Variable Dependent Variable ControlConcentrations of Sucrose Percent Change in Mass ContainersCIndependent Variable Dependent Variable ControlConcentrations of Sucrose Containers Percent Change in MassDIndependent Variable Dependent Variable ControlContainers Concentrations of Sucrose Percent Change in Mass
