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 cm3m3=79/1000000 m3=8.0105 m3  m=h V=532000 0.0001=42.028=42 gh=532 \cdot \ 1000=532000 \ \text{g/m}^3 \ \\ \ \\ V=79 \ cm^3 \rightarrow m^3=79 / 1000000 \ m^3=8.0 \cdot 10^{-5} \ m^3 \ \\ \ \\ m=h \cdot \ V=532000 \cdot \ 0.0001=42.028=42 \ \text{g}
