Students use a balance to determine the mass of a marble in 7.5 g of graduated bottle contains 10 milliliters of water when the marble is carefully lowered into the granulated bottle and is completely covered with water the volume of the water containing the marble has increased to 12.5 ml what is the density of the marble

3 g/ml

Step-by-step explanation:

After the marble was introduced into the graduated bottle, the volume change from 10 ml to 12.5 ml, this means that 12.5 - 10 = 2.5 ml is the volume occupied by the marble.

The mass of a marble is 7.5 g.

Density is defined as follows:

density  = mass / volume =

Replacing with the measures:

density = 7.5/2.5  =  3 g/ml
