The density of any substance can be calculated using the following rule: density = mass / volume Therefore, mass = density x volume First we need to standardize the units: volume = 7.379 x 10^-4 m^3 density = 19.3 gm / cm^3 = 19300 kg / m^3 Now, we will substitute with these values in the above mentioned equation to calculate the mass: mass = density x volume          = 19300 x  7.379 x 10^-4 = 14.24147 kg
