Density - simple example

Material of density of 532 kg/m3 occupies a container volume of 79 cm3. What is its mass?

Result

m =  42 g

Solution:

h=532 1000=532000 g/m3  V=79 cm3=79/1000000 m3=7.9105 m3  m=h V=532000 0.0001=42.028=42  g h = 532 \cdot \ 1000 = 532000 \ g/m^3 \ \\ \ \\ V = 79 \ cm^3 = 79 / 1000000 \ m^3 = 7.9 \cdot 10^{ -5 } \ m^3 \ \\ \ \\ m = h \cdot \ V = 532000 \cdot \ 0.0001 = 42.028 = 42 \ \text { g }
