Answer :

Final answer:

To round off each measurement to three significant figures, follow the rules for significant figures.

Explanation:

To round off each of these measurements to three significant figures, we follow the rules for significant figures:

a.) 98.473L rounds to 98.5L (since 8 is greater than 5, we round up the previous digit).

b.) 0.00076321cg rounds to 0.000763cg (the zeros before the 7 are not significant).

c.) 57.048m rounds to 57.0m (since 0 is less than 5, we do not round up the previous digit).

d.) 12.17°C rounds to 12.2°C (since 7 is greater than 5, we round up the previous digit).

e.) 0.0074983 × mm rounds to 0.00750mm (the zeros after 5 are significant).

f.) 1764.9mL rounds to 1760mL (since 9 is greater than 5, we round up the previous digit).
