Question

Ms. Fleaker set up ten stations for her students to measure the density of 100.0 milliliters of water at different temperatures. The stations were very similar, each having a graduated cylinder, a beaker, a water supply, a hot plate, an ice bath and either an electronic balance that measured to 0.1 gram or a balance that massed to 0.0001 gram.

Ms. Fleaker ran the lab in all five of her classes. Each of the lab groups shared their measurements for mass and volume at the same three assigned temperatures. After examining all the data, there were some differences in the values the groups reported. Ms. Fleaker thought the differences could be explained by
A) not following directions.
B) not conducting enough trials.
C) using balances with different accuracy.
D) not using freezing point and boiling point

Answer 1

answer is B

Step-by-step explanation:

Answer 2

C. using balances with different accuracy.

Step-by-step explanation:

in the question it says "he stations were very similar, each having a graduated cylinder, a beaker, a water supply, a hot plate, an ice bath and either an electronic balance that measured to 0.1 gram or a balance that massed to 0.0001 gram." Not all balances were the same.
