A plastic block of dimensions 2.00 cm × 3.00 cm × 4.00 cm has a mass of 30.0 g.What is its density? A)0.80 g/cm³ B)1.20 g/cm³ C)1.25 g/cm³ D)1.60 g/cm³

Question

Quizplus · Accepted Answer

Density is defined as mass per unit volume. The mass of the block is given as 30.0 g. The volume of the block is calculated by multiplying its dimensions:

Volume = (2.00 cm) × (3.00 cm) × (4.00 cm) = 24.00 cm³

So the density of the block is:

Density = mass / volume = 30.0 g / 24.00 cm³ = 1.25 g/cm³

Therefore, the answer is C, 1.25 g/cm³.
