Question

select the correct number of significant figures in each measurement. match the items in the left column to the appropriate blanks in the sentences on the right. 1 37.06 cm has significant figure(s). 2 0.008 ml has significant figure(s). 3 6.00×10⁻² m has significant figure(s). 4 0.05050 l has significant figure(s). 5 340 kg has significant figure(s). 650 000 km has significant figure(s).

Explanation:

Step1: Identify significant - figure rules for 37.06 cm

Non - zero digits and zeros between non - zero digits are significant. So 37.06 has 4 significant figures.

Step2: Identify significant - figure rules for 0.008 mL

Leading zeros are not significant. So 0.008 has 1 significant figure.

Step3: Identify significant - figure rules for 6.00×10⁻² m

Trailing zeros in a number with a decimal point are significant. So 6.00×10⁻² has 3 significant figures.

Step4: Identify significant - figure rules for 0.05050 L

Leading zeros are not significant, but trailing zeros after a non - zero digit and a decimal point are significant. So 0.05050 has 4 significant figures.

Step5: Identify significant - figure rules for 340 kg

Trailing zeros without a decimal point may or may not be significant. Assuming no decimal point is shown, 340 has 2 significant figures.

Step6: Identify significant - figure rules for 650000 km

Trailing zeros without a decimal point may or may not be significant. Assuming no decimal point is shown, 650000 has 2 significant figures.

Answer:

37.06 cm has 4 significant figure(s).
0.008 mL has 1 significant figure(s).
6.00×10⁻² m has 3 significant figure(s).
0.05050 L has 4 significant figure(s).
340 kg has 2 significant figure(s).
650000 km has 2 significant figure(s).
