Asample of a substance that has a density of 0.824 g/ml has a mass of 0.421 g. calculate the volume of the sample.

Density is a physical property which describes the mass of a substance per unit of volume of the substance. It is expressed as Density = m / V and it has units like g/cm^3. We use the density given to solve the problem.Density = m / V0.824 g/mL = 0.451 g / VV = 0.451 g / 0.824 g/mLV = 0.55 mL

Ifound this on google “laws of chemical combination. it states that matter can neither be created nor destroyed. it stated that a given compound always contains exactly the same proportion of elements by weight.” i hope this you for what your looking for.
