The density of nonadecane, C19H40, is 0.7860 g/mL. Calculate the volume occupied by 9.355 moles of nonadecane.

Answer 1

Density = mass / volume

We know the density and the we can find the mass by converting moles. Then we can find the volume.

molar mass C19H40 = 298.5 g / mol

mass C19H40 = 9.355 mols x 298.5 g / mol = 2792 g

Density = 0.7860 g / ml

2792 g x 1 ml / 0.7860 g = 3552 ml = 3.552 L
