Question

Solve for the following and reporting the correct number of significant figures and units. Explain how the number of significant figures was determined 363.71 g ÷ 40.6 mL =

Answer 1

9.0g/mL

Step-by-step explanation:

Significant figures are determined by using the precision of the least precise measurement (40.6 in this case). If we enter 363.71 ÷ 40.6 into a calculator, we get about 8.95837. We can only use up to the tenths place in our answer since the least precise measurement (40.6) is to the tenths place. So we need to round 8.95837 to the nearest tenth, which is 9.0.
