Question

question 8 (4 points) answer the following questions using the image below. determine the mass (in grams) of the object using the triple beam balance. ____ grams (g) number of sig figs (only use whole numbers) __ lower calibration measurement: __ g upper calibration measurement: ____ g 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 the values on the beams

The top - beam reads 30 g, the middle - beam reads 0 g, and the bottom - beam reads 7 g.

Step2: Calculate the total mass

Add the values from the three beams: $30 + 0+7=37$ g.

Step3: Determine the number of significant figures

The measurement 37 g has 2 significant figures.

Step4: Determine calibration measurements

The smallest division on the bottom beam is 0.1 g. The lower calibration measurement is 36.9 g and the upper calibration measurement is 37.1 g.

Answer:

Blank 1: 37
Blank 2: 2
Blank 3: 36.9
Blank 4: 37.1
