Density Calculations Worksheet
Units of Density
1 ml = 1 cm3
Solids = g/cm3
Liquids = g/mL
Gasses = g/mL
Formulas
_Mass (m)_
Density (D) =
Volume (v)
Volume (v) =
Length (l) x Width (w) x Height (h)
1) Find the unknown quantity:
a) D = ?
v = 95 mL
m = 950 g
b) D = 3 g/mL
v = 100 mL
m=?
c) D = 5 g/cm3
v=?
m = 20 g
d) D = 24 g/mL
e) D = ?
f) D = 250 g/cm3
v = 1200 mL
m=?
v = 100 mL
m = 1500 g
v=?
m = 1000 g
