A small object has a mass of 82.2 grams. When completely immersed in a graduated cylinder with a water level of 25.0 mL, the object causes the water level to rise to 47.1 mL. What is the density of the object in g/mL? (Do not enter the units; only the numeric value.)

3.72

Explanation:

Given data:

Mass of object = 82.2 g

Volume of water = 25.0 mL

Volume of water + object = 47.1 mL

Density of object = ?

Solution:

Volume of object:

Volume of object = (Volume of water + object)  - Volume of water

Volume of object = 47.1 mL -   25.0 mL

Volume of object = 22.1 mL

Density of object:

d = 82.2 g/ 22.1 mL

d = 3.72 g/mL

step-by-step explanation:

whole numbers, zero or greater
