Answer

Explanation:

Step1: Recall significant - figures rules

Non - zero digits are always significant. Zeros between non - zero digits are significant. Trailing zeros after a decimal point are significant. Leading zeros are not significant. Trailing zeros in a whole number without a decimal point may or may not be significant (in this case, we assume they are not significant unless there is a decimal point).

Step2: Analyze 9.50 mL

Non - zero digits 9 and 5 are significant, and the trailing zero after the decimal is also significant. So, there are 3 significant figures.

Step3: Analyze 10.0 g

Non - zero digits 1 is significant, and the zeros after the decimal are significant as they are between non - zero digits and trailing after a decimal. So, there are 3 significant figures.

Step4: Analyze 0.30 L

The leading zero is not significant. Non - zero digit 3 and the trailing zero after the decimal are significant. So, there are 2 significant figures.

Step5: Analyze 2.5°C

Non - zero digits 2 and 5 are significant. So, there are 2 significant figures.

Step6: Analyze 2380 g

The trailing zero is not significant as there is no decimal point. Non - zero digits 2, 3, and 8 are significant. So, there are 3 significant figures.

Step7: Analyze 2.90 g

Non - zero digits 2 and 9 are significant, and the trailing zero after the decimal is significant. So, there are 3 significant figures.

Step8: Analyze 500 mL

The trailing zeros are not significant as there is no decimal point. Only the non - zero digit 5 is significant. So, there is 1 significant figure.

Step9: Analyze 76 g

Non - zero digits 7 and 6 are significant. So, there are 2 significant figures.

Step10: Analyze 0.077 kg

The leading zeros are not significant. Non - zero digits 7 and 7 are significant. So, there are 2 significant figures.

Step11: Analyze 7.10 mL

Non - zero digits 7 and 1 are significant, and the trailing zero after the decimal is significant. So, there are 3 significant figures.

Step12: Analyze 1.330×10²⁴ ns

Non - zero digits 1, 3, and 3 are significant, and the trailing zero after the decimal is significant. So, there are 4 significant figures.

Step13: Analyze 67.8 g

Non - zero digits 6, 7, and 8 are significant. So, there are 3 significant figures.

Step14: Analyze 505 g

Non - zero digits 5, 0, and 5 are significant (the zero is between non - zero digits). So, there are 3 significant figures.

Step15: Analyze 3.03 mL

Non - zero digits 3 and 3 are significant, and the zero between them is significant. So, there are 3 significant figures.

Step16: Analyze 0.0400 L

The leading zeros are not significant. Non - zero digit 4 and the two trailing zeros after the decimal are significant. So, there are 3 significant figures.

Step17: Analyze 500.0 g

Non - zero digit 5 is significant, and the trailing zeros after the decimal are significant. So, there are 4 significant figures.

Step18: Analyze 4.3×10² mL

Non - zero digits 4 and 3 are significant. So, there are 2 significant figures.

Step19: Analyze 120°C

The trailing zero is not significant as there is no decimal point. Non - zero digits 1 and 2 are significant. So, there are 2 significant figures.
