A manufacturer selected a metal to use in producing a lightweight button for clothing. A metal that has a density of 2.71 g/cm3 was selected. metal, data, metal, mass, grams, volume, centimenters, cubed, 1, 22.1, 3.00, 2, 42.0, 4.00, 3, 9.32, 5.00, 4, 8.13, 3.00,
Which of the metals was selected?
Metal 1
Metal 2
Metal 3
Metal 4

Just find the density of every metal and select the one with a density of 2.71 g/cm³ . This is:

Metal 1

ρ = m/V

ρ = 22.1 g / 3 cm³

ρ = 7.367 g / cm³

Metal 2

ρ = m/V

ρ = 42 g / 4 cm³

ρ = 10.5 g / cm³

Metal 3

ρ = m/V

ρ = 9.32 g / 5 cm³

ρ = 1.864 g / cm³

Metal 4

ρ = m/V

ρ = 8.13 g / 3 cm³

ρ = 2.71 g / cm³
