Question

question 11 (4 points)
answer the following questions using the image below:
determine the volume (in ml) in the graduated cylinder. ______ ml
number of sig figs (only use whole numbers) ______
lower calibration measurement: ______ ml
upper calibration measurement: ______ ml
be sure to go to the appropriate amount of sig figs. remember, sig figs include all known digits, plus one estimated digit.

Explanation:

Step1: Read volume from cylinder

The meniscus is at the 67 - 68 mL mark. Estimating, the volume is 67.5 mL.

Step2: Determine significant figures

The measurement 67.5 has 3 significant figures. The known digits are 67 and the 5 is the estimated digit.

Step3: Identify lower calibration

The lowest visible calibration mark is 60 mL.

Step4: Identify upper calibration

The highest visible calibration mark is 80 mL.

Answer:

Volume: 67.5 mL
Number of Sig Figs: 3
Lower Calibration Measurement: 60 mL
Upper Calibration Measurement: 80 mL
