Two students in the same class find that a piece of wood, with a mass of 70 g, has a volume of 103 cm₃. They conclude that the wood is oak.
Is this accurate?
Why?

The wood is oak.

Explanation:

Given data:

Mass of wood = 70 g

Volume of wood = 103 cm³

Wood is oak = ?

Solution:

We will calculate the density of wood then we will compare it with literature value.

Density = mass/ volume

d = 70 g/ 103 cm³

d = 0.68 g/cm³

The density of oak is 0.59 - 0.90 g/cm³.

So its true, wood is oak.
