The density of quartz is 165 lb/ft³.A clear crystal with a mass of 26.5 g is found to displace 10.0 cm³ of water.The crystal has a density __________ (1 lb = 453.6 g; 1 m³ = 1 *10⁶ cm³ = 35.31 ft³)

Question

The density of the crystal is:$$d = \frac{m}{V} = \frac{26.5 g}{10.0 cm^3} = 2.65 g/cm^3$$Converting to lb/ft^3:$$d = 2.65 g/cm^3 	imes \frac{1 lb}{453.6 g} 	imes \frac{(35.31 ft)^3}{(1 m)^3} = 165 lb/ft^3$$Therefore, the crystal has a density of 165 lb/ft^3, which is the same as the density of quartz.
