Introduction to Density. Density is the measurement of the mass of an object per unit volume of that object. d = m / V Density is usually measured in g/mL or g/cm 3 for solids or liquids. Volume may be measured in the lab using a graduated cylinder or calculated using:
d = m / V
d = m / V = 50.0 g / 52.0 mL = 0.98 g/mL
V=pr2h = p(1.70 cm/2)2* (2.03 in [2.54 cm/1in]) =11.7 cm3 D = m/V = 31.599 g / 11.7 mL = 2.70 g/mL
The metal is aluminum!
