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.
