Question

A student calculates the density of an unknown solid. The mass is 10.04 grams, and the volume is 8.21 cubic centimeters. How many significant figures should appear in the final answer

Answer 1

Answer:

1.22 g/cm³

Explanation:

Density = mass ÷ volume

Mass = 10.04 grams

Volume = 8.21 cubic centimeters

Density = mass ÷ volume

= 10.04 ÷ 8.21

= 1.2228989037758 g/cm³

Approximately

1.22 g/cm³ to 2 significant figure.

The final answer should be approximated to 2 significant figure because the mass and volume of the objective given is in 2 significant figure
