Question

Some metal chips with a total volume of 3.29 cm3 are placed on a piece of paper and weighed. The combined mass is found to be 18.43 g, and the paper itself weighs 1.2140 g. Calculate the density of the metal to the proper number of significant figures.

Answer 1

mass of metal chips is 18.4300g - 1.2140g = 17.2160g

density is (17.2160 g)/(3.29 cm3) = 5.23 g/cm3
