Question

what is the calibration of this graduated cylinder?
calibration = (difference between 2 marked values)/(# of spaces between marked values)
options: 1 ml, 2 ml, 10 ml, 3 ml

Explanation:

Step1: Find the difference between marked values

The marked values are 65 mL and 60 mL (or 70 mL and 65 mL, same difference). The difference is $65 - 60 = 5$ mL.

Step2: Count the number of spaces between marked values

Looking at the graduated cylinder, between 60 and 65 (or 65 and 70), there are 5 spaces.

Step3: Calculate calibration

Using the formula $calibration=\frac{\text{difference between 2 marked values}}{\text{\# of spaces between marked values}}$, we substitute the values: $\frac{5}{5}=1$ mL.

Answer:

1 mL
