The density of the iron is 7.8 g/mL.
The density of an object is defined as mass per unit volume of the object i.e
Density = mass / volume
To solve the question given above, we'll begin by calculating the volume of the iron. This can be obtained as follow:
Volume of water = 23.80 mL
Volume of water + Iron = 24.59 mL
Volume of iron =?
Volume of iron = (Volume of water + Iron) – (Volume of water)
Volume of iron = 24.59 – 23.80
Volume of iron = 0.79 mL
Finally, we shall determine the density of the iron. This can be obtained as follow:
Volume of iron = 0.79 mL
Mass of iron = 6.2 g
Density of iron =?
Density = mass / volume
Density = 6.2 / 0.79
Density of iron = 7.8 g/mL
Therefore, the density of the iron is 7.8 g/mL
