Explanation:
Detailed explanation-1: -If it had been written as 0.510 it would also have three significant figures because zeros after nonzero digits to the right of a decimal point are significant. Write the other numbers in scientific notation to determine the number of significant figures.
Detailed explanation-2: -The zeros that are present on the left-hand side of the significant figure are not considered significant, and those present on the right side are considered significant. In 0.0080 kg, the two significant figures are 8 and 0. Thus, there are 2 significant figures in 0.0080 kilograms.
