908. It is known that the molar refraction of a liquid is approximately equal to its molar volume. Based on this, calculate the radius of a molecule of a substance (solvent), based on the density p and the refractive index n of light, indicated below for the corresponding problem number and assuming that the molecule has a spherical shape.
908. n-butanol C4H10O
p, g/cm3 0.816
n 1.4029
