density of indium?

Question

The weight of a slice of idium metal is 17.289 g. It is placed into 41.1cm^3 of ethyl alcohol (d=.789 g/cm^3) in a graduated cylinder.

The alcohol is up to 43.4cm^3.

What is a density of indium?

Answer 1

m = 17.289 g

V = 43.4 cm³ - 41.1 cm³ = 2.30 cm³

ρ = m/V = (17.289 g) / (2.30 cm³) ≅ 7.52 g/cm³
