Answer
Explanation:
Step1: Identify significant - figures 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 (zeros after non - zero digits) are significant if there is a decimal point.
Step2: Analyze 24.56 g
All digits are non - zero. So, the number of significant figures is 4.
Step3: Analyze 3.01 mL
The zero is between non - zero digits. So, the number of significant figures is 3.
Step4: Analyze 0.0358 kg
The leading zeros are not significant. So, the number of significant figures is 3.
Step5: Analyze 2.00 mL
The trailing zeros are significant because of the decimal point. So, the number of significant figures is 3.
Step6: Analyze 101.0 g
The zero between non - zero digits and the trailing zero (due to the decimal point) are significant. So, the number of significant figures is 4.
Step7: Analyze 220 g
The trailing zero is not significant as there is no decimal point. So, the number of significant figures is 2.
Step8: Analyze 3.10×10⁻³ kg
In scientific notation, all digits in the coefficient are significant. So, the number of significant figures is 3.
Step9: Analyze 0.031 kg
The leading zeros are not significant. So, the number of significant figures is 2.
Step10: Analyze 4.40×10²²
In scientific notation, all digits in the coefficient are significant. So, the number of significant figures is 3.
Step11: Analyze 9.50 mL
The trailing zero is significant due to the decimal point. So, the number of significant figures is 3.
Step12: Analyze 10.0 g
The zero between non - zero digits and the trailing zero (due to the decimal point) are significant. So, the number of significant figures is 3.
Step13: Analyze 0.30 L
The trailing zero is significant due to the decimal point. So, the number of significant figures is 2.
Step14: Analyze 2.5°C
All non - zero digits are significant. So, the number of significant figures is 2.
Step15: Analyze 2380 g
The trailing zero is not significant as there is no decimal point. So, the number of significant figures is 3.
Step16: Analyze 2.90 g
The trailing zero is significant due to the decimal point. So, the number of significant figures is 3.
Step17: Analyze 500 mL
The trailing zeros are not significant as there is no decimal point. So, the number of significant figures is 1.
Step18: Analyze 76 g
Both digits are non - zero. So, the number of significant figures is 2.
Step19: Analyze 0.077 kg
The leading zeros are not significant. So, the number of significant figures is 2.
