A student obtained an unknown solid from the room and determined its mass to be 57.96g. ?

Question

When the solid was placed in a 60.0mL of water the total volume was 74.5mL. What is the density of the metal?

Answer 1

74.5 mL = volume of water + volume of solid

60.0 = volume of water

volume of solid = 74.5 - 60.0 = 14.5 ml (14.5 cm^3)

57.96 g / 14.5 cm^3 = 4.00 g/cm^3 (the density of the solid)
