Question

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 triple - beam balance values

The top beam reads 60 g, the middle beam reads 300 g, and the bottom beam reads 3.4 g.

Step2: Calculate total mass

Total mass = 60 + 300+3.4 = 363.4 g

Step3: Determine number of significant figures

The measurement 363.4 has 4 significant figures as all non - zero digits are significant.

Step4: Find calibration measurements

The smallest division on the bottom beam is 0.1 g. The lower calibration measurement is 3.3 g and the upper calibration measurement is 3.5 g.

Answer:

Blank 1: 363.4
Blank 2: 4
Blank 3: 3.3
Blank 4: 3.5
