2.A piece of anthracite has a volume of 16cm^3 and a mass of 30 g. What is the density in. i) g/cm^3 ii) kg/m^3

To find the density of the anthracite, we can use the formula:Density = Mass / VolumeGiven:Mass = 30 gVolume = 16 cm^3i) To find the density in g/cm^3, we can use the formula:Density = Mass / VolumeDensity = 30 g / 16 cm^3Density = 1.875 g/cm^3Therefore, the density of the anthracite in g/cm^3 is 1.875.ii) To find the density in kg/m^3, we need to convert the units:1 g = 0.001 kg1 cm^3 = 0.000001 m^3Density = Mass / VolumeDensity = 30 g * 0.001 kg/g * 1 / (16 cm^3 * 0.000001 m^3/cm^3)Density = 30 * 0.001 kg / (16 * 0.000001 m^3)Density = 30 * 1000 kg/m^3 / 16Density = 1875 kg/m^3Therefore, the density of the anthracite in kg/m^3 is 1875.
