Question

A block of aluminium occupies a volume of 11.1 mL and weighs 43 g. What is it's density? Give answer with one decimal.

Answer 1

Answer:

Density = 3.9 g/ mL

Explanation:

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

$Density = \frac{mass}{volume}$

From the question

mass = 43 g

volume = 11.1 mL

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

That's

$Density = \frac{43}{11.1} \\ = 3.873873...$

We have the final answer as

Density = 3.9 g/ mL to one decimal place

Hope this helps you
