Toni is performing part A of FPD. He transferred 19.8 mL of water to the sample test tube and froze the liquid twice. For trials 1 and 2, Toni determined the freezing point of distilled water to be 0.9 °C and 0.7 °C, respectively. What is the average freezing point of the distilled water?

0.8°C

Explanation:

Given the following:

Trial 1 : freezing point of distilled water = 0.9°C

Trial 2: freezing point of distilled water = 0.7°C

The average freezing point of distilled water is the sum of the two freezing points obtained divided by 2 ;

(Trial 1 + trial 2) / 2

(0.9°C + 0.7°C) / 2

1.6°C / 2

= 0.8°C
