P.The density of a material can be used to calculate the volume of an object if its massis known. Likewise, the mass can be calculated if the density and volume are known.A pre-1964 quarter, made predominantly of silver (density = 10.5 g/ml), wasdetermined to have a mass of 6.25 g. What is the volume of the quarter?a) 0.595 mLb) 1.68 mLc) 6.25 mLd) 65.6F10FILgO F3F8000F4F7F5F6F2&*$4#3%78YU
