Question 7 of 13beginner🔧 ApplyNumerical2 marks

An object has a mass of 400 g and a volume of 40 cm³. What is its density?

Correct Answer

Using the formula Density = Mass/Volume from the chapter, we divide the mass by the volume to find the density.

Step 1: Identify the given values - Mass = 400 g, Volume = 40 cm³.

Step 2: Apply the density formula: Density = Mass/Volume.

Step 3: Calculate: Density = 400 g ÷ 40 cm³ = 10 g/cm³.

The density of the object is 10 g/cm³.
