Milk has a density of 1.035 g/ml and olive oil has a density of 0.850 g/ml. Which has more mass

Milk.

Explanation:

Density is used to describe how much space an object or substance takes up in relation to the amount of matter in that object or substance (its mass).

Another way to put it is that, density of a substance is the amount of mass of that substance per unit volume. If an object is heavy and compact, it has a high density.

Density = mass/volume

So,

Milk = 1.035 g of milk per 1 ml

Olive oil = 0.85 g of olive oil in 1 ml.

Therefore, milk has a higher mass.
