Question

Which volume is reported with greater precision, 87.0 mL or 87.04 mL? Why?

a) 87.0 mL is more precise because it has more decimal places.
b) 87.04 mL is more precise because it has more significant figures.
c) Both volumes have the same precision.
d) Neither volume is precise.

Answer 1

87.04 mL is more precise because it has more significant figures.

Step-by-step explanation:

87.04 mL is more precise because it has more significant figures. The number of significant figures in a measurement reflects the level of precision. In this case, the measurement with more significant figures, 87.04 mL, indicates a higher level of precision compared to 87.0 mL.
