The volume of a quartz mineral sample was determined placing the weighed sample in a graduated cylinder containing 56.3 mL water. With the mineral sample completely submerged, the water level was 68.2 mL. THis measuring method, known as water displacement, uses the volume of an irregular object. The dry mass of the quartz sample was 31.18 g. What was the density of the quartz in g/cm^3?
