Answer
a) 73.0 mL
b) 88.2 C
c) 645 mL
Work Step by Step
The liquid is between 73 mL and 74 mL. The meniscus is approximately at 73 mL. The .0 is an estimation.
The liquid is between 500 mL and 600 mL. The meniscus is approximately between 640 mL and 650 mL. You can estimate the last digit as 5, so the reading is 645 mL.
