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 = [tex]\frac{mass in g}{volume in cm^{3} }[/tex]
The unknown in the problem is Volume:
Volume = [tex]\frac{mass}{Density}[/tex]
Volume = [tex]\frac{17.8}{8.9}[/tex] = 2cm³
