Question

calculate the density if the mass of a solid material is measured as 15.00 grams and its volume is measured as 5.0 cm3? Round off your answer to the proper number of significant figures.

Answer 1

D= M/V

Mass= 15.00 grams

Volume= 5.0 cm^3

D= 15.00g/5.0 cm^3

D= 3.00g/1.0 cm^3

maximum of 2 sig figs (5.0) so it is 3.0 g/cm^3, or, because one cm^3 is 1 mL: 3.0 g/mL
