Answer : The density of iron is, 7.8 g/mL
Explanation : Given,
Mass of iron = 4.7 g
Volume of water = 27.10 mL
Volume of water and iron = 27.70 mL
First we have to calculate the volume of iron.
Volume of iron = Volume of water and iron - Volume of water
Volume of iron = 27.70 mL - 27.10 mL
Volume of iron = 0.6 mL
Now we have to calculate the density of iron.
Now put all the given values in this expression, we get:
Thus, the density of iron is, 7.8 g/mL
