John is testing the effect of temperature on the solubility of sugar in water,
he plans to determine the mass of sugar dissolved in a saturated solution.
he will begin with a known mass of sugar and add sugar to water until the
solution is saturated. he will then calculate how much sugar dissolved by
subtracting the remaining mass from the initial mass
he organized data about his experiment in the following table:
group a
group b
group c
volume of water 100 ml
25°c
1000 g
temperature
initial mass of
sugar
final mass of
sugar
800 g
which factor should be the same in all three groups?
o
a. final mass of sugar
o
b. initial mass of sugar
o
o
c. volume of water
d. temperature
