Answer:

d = 5.23 g/cm³

Explanation:

Given data:

Volume of metal chips = 3.29 cm³

Mass of metal chips and paper = 18.43 g

Mass of paper = 1.2140 g

Density of metal = ?

Solution:

Mass of metal = combined mass - mass of paper

Mass of metal = 18.43 g - 1.2140 g

mass of metal = 17.22 g

Density:

d = mass/ volume

d = 17.22 g/ 3.29 cm³

d = 5.23 g/cm³
