Question

Indicate if the zeros are significant or not in each of the following measurements. Drag the appropriate measurements to the respectable bins.

Answer 1

• All zeros are significant:

5.04 cm.

800. L

• No zeros are significant:

3.0x10^-3 kg

0.0038 m

85000 g

Step-by-step explanation:

To identify in which case the zeros are significant or not, we have to analyze each case:

• 5.04 cm,: in this case, the zero is significant, because it is between 2 significant figures.

,

• 3.0x10^-3 kg,: we can write this number like 0.003 kg to identify the zeros easily. In this case, no zeros are significant, because zeros to the left of the first significant figure are not significant.

,

• 800. L,: In this case, all zeros are significant because there is a decimal point at the end of the number.

,

• 0.0038 m,: here no zeros are significant, because zeros to the left of the first significant figure are not significant.

,

• 85000 g,: in this case, no zeros are significant, because zeros at the end of a number are meaningless if the number does not contain a decimal point.
