Calculate the density of propanol c3h8o if you know that there are 1.069×1025 molecules of propanol in 1.35 l.

Density is a physical property which describes the mass of a substance per unit of volume of the substance. It is expressed as Density = m / V. We calculate as follows:

Density = 1.069×10^25 molecules ( 1 mol / 6.022x10^23 molecules ) (60.11 g / mol) / 1.35 L = 790.41 g/L

Particle exchange energy though elastic collision , hope this .
