Density, or volumic mass (ISO 31), is a measure of mass per volume. The average density of an object equals its total mass divided by its total volume. An object made from a comparatively dense material (such as iron) will have more mass than an equal-sized object made from some less dense substance (such as aluminium).
Density = mass/ volume, or D=m/V
So D= 75gr/35ml
D= 2.14 gr per ml

D=m/V=75/35=15/7=2.14285

Density = mass/volume
The volume of the object = the volume of water displaced
So the volume of the object is 35ml = 35cm^3
Density = 75/35
= 2.14g/cm^3

desity = mass/volume. mass=75g,vol=35ml. so the density is 75/35= 2.1g/ml.

This means that the volume of the rock is 35 ml which is also 35 cc. Hence the density is 2.15 gm / cc (you get this by dividing mass / volume). This can be converted to other units such as SI, applying suitable conversions.
Say I want to convert this to SI units. Then it would be 2.15 * 10^-3 kg / 10^-6 metre cube. This equals to 2.15 * 10 ^3 or 2150kg/metre cube.
