Determine the number of significant digits in the measurement. 80.00 kg a. 1 b. 3 c. 4 d. 2

The correct answer is c. 4 significant figures

Step-by-step explanation:

The trailing zeros after the decimal point, which means on the decimal portion are significant. This is the rule that will help us identify the number of significant figures for the exercise.

Counting the significant figures.

The first digit on this exercise is 8,

80.00

All non zero digits are always a significant figure. Thus for that digit we have one significant figure.

After the 8, we have zeros, however, we have a decimal point and trailing zeros in the decimal portion.

80.00

There are 2 trailing zeros on the decimal portion, and since trailing zeros after the decimal point are significant, there are as well 2 significant figures, and there is a zero between two significant digits which is also significant, there fore we have in total of 3 significant figures for the zeros.

If we add all of the significant figures from those rules, we get a total of 4 significant figures, thus the answer is c) 4 Significant figures.
