Question

1. Suppose you have a metal bar. Its mass is 57.9g and its volume is 3cm'. What is its density?

Answer 1

¡Hellow!

How we know, for calculate density, we can use the formule:

                                               $\boxed{\textbf{p = m / v} }$

Where:

$\sqrt{$ p = Density = ?

$\sqrt{$ m = Mass = 57,9 g

$\sqrt{$ v = Volume = 3 cm³

Let's replace according we information:

p = 57,9 g / 3 cm³

p = 19,3 g/cm³

The density of the metal bar is 19,3 g/cm³.

¿Good luck?
