What is the density of the object when mass of 7.5g raises the level of water in a graduated cylinder from 25.1mL to 30.1mL

1 answer

Density can be calculated using the formula:

Density = mass / volume

In this case, the mass is 7.5g and the volume is the difference in water level in the graduated cylinder. The volume displaced is the difference between the final volume (30.1mL) and the initial volume (25.1mL), which is 5mL.

Thus, the volume is 5mL or 5cm^3 (since 1mL = 1cm^3).

Density = 7.5g / 5cm^3 = 1.5 g/cm^3

Therefore, the density of the object is 1.5 g/cm^3.
