Question

Density (D) is defined as the ratio of mass (m) to volume (V) and can be determined from the expression D = . Find the density of a sample of pure aluminum if a rectangular prism of volume 32.32 cm3 occupies a mass of 87.329 g. (Remember to put a space between your numerical value and the unit.)

Answer 1

That is a question about density.

To solve that question, it is important to know how we can obtain the Density of an object. Below, you can see the formula:

$\boxed{D=\frac{m}{v} }$

$D = Density\\m = Mass\\V = Volume$

Now, it is easy to answer, right? We just replace the values in the formula. The mass is 87.329g and the volume is 32.32cm³. So,

$D=\frac{m}{v} \\\\D = \frac{87.329g}{32.32cm^3} \\\\D \approx 2.70g/cm^3$

Therefore, the density of the the aluminium is approximately 2.7 g/cm³.

I hope I've helped. ^^
