2
Q
What units do you use to represent concentration?
A
M
3
Q
What is the least amount of time that the potatoes must remain in the sucrose solution for?
A
At least 40 minutes
4
Q
What must you do after the experiment?
A
Pat dry gently
5
Q
What is the independent variable?
A
The sucrose solution concentration
6
Q
How do you find the percentage change in mass?
A
You minus the initial mass from the final mass then divide that by the initial mass. finally you must times by 100
