Question

question 7
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 each beam

The top beam reads 80 g, the middle beam reads 100 g, and the bottom beam reads 7.9 g.

Step2: Calculate the total mass

Add the values from each beam: $80 + 100+7.9=187.9$ g.

Step3: Determine the number of significant - figures

The measurement 187.9 g has 4 significant figures.

Step4: Identify lower and upper calibration measurements

The smallest division on the bottom beam is 0.1 g. The lower calibration measurement for the bottom - beam reading of 7.9 g is 7.85 g and the upper calibration measurement is 7.95 g.

Answer:

Blank 1: 187.9
Blank 2: 4
Blank 3: 7.85
Blank 4: 7.95
