a volume of 64cm3 has a mass of 672g the density of pure silver is known to be 10.5g/cm3 based on this information could the metal be pure silver

using the 10.5g/cm³ find the mass of silver so we have to find the mass of the sample  M = V x D  M = 64 x 10.5 =627g so the sample is pure silver as its theoretical mass based on its density is equal to the mass of the sample  hope that helps
