A marble was dropped into a graduated cylinder holding a volume of 20 mL. The water level increased to 35 mL. The mass of the marble is 37.8 grams. What is the density of the marble?

2.52 g/ml

Step-by-step explanation:

Density is defined as the mass per unit volume of a substance. Therefore,

density, d=m/v

Where d denote density, m for mass and v for volume.

The volume of marble is given by getting the difference in the reading of graduated cylinder. Since the initial reading was 20 ml and final reading 35 ml, rhen the volume is 35-20=15 ml

The mass is given as 37.8 grams.

Density is therefore 37.8 g/15ml=2.52 g/ml

Density of marble is 2.52 g/ml
