Find the mass of 250.0 mL of benzene. The density of benzene is 0.8765 g/mL.
D= m/v
m= vD
m = (0.8765 g/mL) (250.0 mL) = 219.1 g
Convert 6Mg to kg

28.5 g of iron shot is added to a graduated cylinder containing 45.50 mL of water. The water level rises to the 49.10 mL mark, From this information, calculate the density of iron.
vol of iron shot = 49.10 mL - 45.50 mL = 3.60 mL
d = 28.5 g / 3.60 mL
d = 7.92 g/mL

A block of lead has dimensions of 4.50 cm by 5.20 cm by 6.00 cm. The block weighs 1587 g. From this information, calculate the density of lead.
(4.50 cm) (5.20 cm) (6.00 cm) = 140.4 cm3
d = 1587 g / 140.4 cm3 = 11.3 g/cm3
Convert a density of 4.52 g/mL to its equivalent in kg/L.
