To determine the density of a substance, you need to divide the mass by the volume. In this case, the density would be 40 grams / 20mL = 2 grams per milliliter (g/mL). Density is a physical property that describes the amount of mass per unit volume of a substance.

density = mass/volume = 2g/40cm3 = 0.05g/cm3
its 2.3g/ML
Well, isn't that a happy little question! To find the density, you simply divide the mass of the object by its volume. In this case, if the mass is 120 grams and the volume is 40 cm3, the density would be 3 grams per cubic centimeter. Just remember, there are no mistakes, just happy little accidents in math!
Density = Mass/Volume = 200 g / 5 cm3 = 40 gcm-3
