Question

?cobalt has a density of 8.90 g. what volume would 17.8 g of Cobalt occupy?

Answer 1

Answer:

Explanation:

Given parameters:

Density of cobalt = 8.9gcm⁻³

Mass of cobalt = 17.8g

Solution

Density can be defined as the mass per unit volume of a substance:

                      Density = $\frac{mass in g}{volume in cm^{3} }$

The unknown in the problem is Volume:

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

                     Volume =   $\frac{17.8}{8.9}$ = 2cm³
