Density of liquids and gases.
Data:
d = ?
m = 40.0 g
v = 80.0 cm³
The formula for the density of liquids and gases
d = m/v
Since it asks us to calculate the density, it is not necessary to clear the formula. We just substitute data and solve.
d = 40.0 g/80.0 cm³
d = 0.5 g/cm³
The density of an object with a mass of 40.0 g and a volume of 80.0 cm^3 is 0.5 g/cm^3.
