Quizplus · Accepted Answer

Specific gravity = Weight in air / Weight in water19.3 = 0.639 / Weight in waterWeight in water = 0.639 / 19.3 = 0.0331 NSpecific gravity = Weight in air / Weight in water13.6 = 0.639 / Weight in waterWeight in water = 0.639 / 13.6 = 0.04698 NVolume = Weight in water / Density of waterVolume = 0.04698 / 1000 = 45.9 cm³Mass = Volume * DensityMass = 45.9 * 13.6 = 624.24 g
