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. 37.06 cm has significant figure(s) 0.098 ml has significant figure(s) 0.00×10⁻² m has significant figure(s) 0.05050 l has significant figure(s) 340 kg has significant figure(s) 650000 km has significant figure(s)

Explanation:

Step1: Identify significant - figure rules

Non - zero digits are always significant. Zeros between non - zero digits are significant. Leading zeros (zeros before non - zero digits) are not significant. Trailing zeros in a number with a decimal point are significant. Trailing zeros in a number without a decimal point may or may not be significant (usually considered not significant for measurements).

Step2: Analyze 37.06 cm

The non - zero digits 3, 7, 6 and the zero between 7 and 6 are significant. So, 37.06 cm has 4 significant figures.

Step3: Analyze 0.098 mL

The leading zeros are not significant. Only 9 and 8 are significant. So, 0.098 mL has 2 significant figures.

Step4: Analyze 0.00×10⁻² m

The leading zeros are not significant. If it's written as 0.00, it has 0 significant figures as there are no non - zero digits shown.

Step5: Analyze 0.05050 L

The leading zero is not significant. The non - zero digits 5, 5 and the trailing zero after the last 5 (since there is a decimal point) are significant. So, 0.05050 L has 4 significant figures.

Step6: Analyze 340 kg

The trailing zero without a decimal point is not considered significant. So, 340 kg has 2 significant figures.

Step7: Analyze 650000 km

The trailing zeros without a decimal point are not considered significant. So, 650000 km has 2 significant figures.

Answer:

37.06 cm has 4 significant figures
0.098 mL has 2 significant figures
0.00×10⁻² m has 0 significant figures
0.05050 L has 4 significant figures
340 kg has 2 significant figures
650000 km has 2 significant figures
