Can someone please show me how to solve these? Thanks!

Question

1.) A 14.3-cm³ sample of tin has a mass of 0.100kg

density= _____g/mL

2.) a bottle of acetone contains 55.0ml of acetone with a mass of 43.3g

density=_______g/ml

Answer 1

Density = mass/volume (memorize this). Also, cm³ is the same as mls.

1.) mass/volume = 0.100kg x 1000g/kg = 100 g/14.3cm³ = 6.99 g/cm³ = density in g/ml (cm³ = ml)

2.) mass/volume = 43.3 g/55.0 ml = 0.787 g/ml = density
