  • Problem: A piece of copper has a mass of 57.54 g. It is 9.36 cm long, 7.23 cm wide, and 0.95 mm thick. Calculate density (g/cm3).

  • Problem A piece of copper has a mass of 57.54 g. It is 9.36 cm long, 7.23 cm wide, and 0.95 mm thick. Calculate density (g/cm3).

    G=U=E=S=S=M= 57.54 g, Length= 9.36 cm Width= 7.23 cm, Thickness0.95 mm Density= ? (g/cm3)Density= mass volumeVolume = l x w x h0.95 mm x 1 m x 102 cm 103 mm 1 m=0.095 cm3Volume = 9.36 cm x7.23 cm x 0.095 cm = 6.4 cm3 Density= 57.54 g 6.4 cm3=8.990625 or 9.0 g/cm3
