Question

determine the volume (in ml) in the graduated cylinder.
number of sig figs (only use whole numbers)
lower calibration measurement:
upper calibration measurement:
be sure to go to the appropriate amount of sig figs. remember, sig figs include all known digits, plus one estimated digit.

Explanation:

Step1: Determine the volume reading

The meniscus of the liquid in the graduated - cylinder is between 8.4 mL and 8.5 mL. Estimating the digit, the volume is 8.45 mL.

Step2: Identify the number of significant figures

The measurement 8.45 mL has 3 significant figures. The non - zero digits 8, 4, and 5 are all significant.

Step3: Find the lower calibration measurement

The lowest visible calibration mark below the meniscus is 8 mL.

Step4: Find the upper calibration measurement

The highest visible calibration mark above the meniscus is 9 mL.

Answer:

Blank 1: 8.45
Blank 2: 3
Blank 3: 8
Blank 4: 9
