Question

An object with a mass of 5.6 g raises the level of water in a graduated cylinder from 25.1 mL to 33.9 mL. What is the density of the object?

Answer 1

Answer:

0.6364 g/cm^3

Explanation:

Density = mass/volume

Where mass = 5.6g and...

Volume = (33.9 - 25.1) = 8.8ml

Where 1ml = 1 cm^3

Density = 5.6/8.8 = 0.6364 g/cm^3

Answer 2

Answer:

0.64 g/cm³

Explanation:

Density is defined as mass divided by volume. The mass of the object we know (5.6 g). In order to find the volume it occupies, we consider the water displaced in the graduated cylinder. The object raised the level of water by the same volume that it occupies. So the volume of the object is then:

(33.9 mL - 25.1 mL) = 8.8 mL

The density of the object is then calculated:

D = m/V = (5.6 g)/(8.8 mL) = 0.64 g/mL = 0.64 g/cm³
