The density of quartz mineral was determined by adding a weighed piece to a graduated cylinder containing 52.6 mL water. After the quartz was submerged, the water level was 67.5 mL. The quartz piece weighed 38.5 g. What was the density of the quartz?

Answer 1

water displaced: 67.5-52.6 = 14.9 cm^3
so, density is 35.8g/14.9cm^3 = ____ g/cm^3
