Question

An unknown material has a mass of 2.75 g and a volume of 4 cm3. What is the density of the material? Round to the nearest tenth.

Answer 1

Answer:
density = 0.7 gm/cm³

Step-by-step explanation:
Density can be calculated using the following rule:
Density = mass / volume

We are given that:
mass = 2.75 grams
volume = 4 cm³

Substitute with the givens in the above equation to get the value of the density as follows:
density = 2.75 / 4
density = 0.6875 which is approximately 0.7 gm/cm³

Hope this helps :)
