# A Block of Aluminium Density Calculation

What is the density of a block of aluminium that occupies a volume of 11.1 mL and weighs 43 g?

Density = 3.9 g/mL

## Explanation:

**The density of a substance** can be found by using the formula:

**Density = mass / volume**

From the question:

mass = 43 g

volume = 11.1 mL

Substitute the values into the formula and solve for the density:

That's:

**Density = 43 / 11.1**

**= 3.873873...**

We have the final answer as:

**Density = 3.9 g/mL** to one decimal place.

Hope this helps you!
