To determine the number of significant figures in the answer for the calculation \(41.0 \div 0.302\), we need to look at the number of significant figures in each of the numbers involved in the operation.
- 41.0 has 3 significant figures (the "41" are significant, and the trailing zero after the decimal point is also significant).
- 0.302 has 3 significant figures (the "3", "0", and "2" are all significant).
When performing division, the result should be expressed with the same number of significant figures as the number with the fewest significant figures involved in the calculation. In this case, both \(41.0\) and \(0.302\) have 3 significant figures.
Therefore, the answer to \(41.0 \div 0.302\) should be expressed with 3 significant figures.
