Answer:
7.92 g/mL.
Explanation:
The following data were obtained from the question:
Mass of Iron = 28.5 g
Volume of water = 45.5 mL
Volume of water + Iron = 49.1 mL.
Density of Iron =.?
Next, we shall determine the volume of the iron. This can be obtained as illustrated below:
Volume of water = 45.5 mL
Volume of water + Iron = 49.1 mL.
Volume of iron =.?
Volume of iron = (Volume of water + Iron) – (volume of water)
Volume of iron = 49.1 – 45.5
Volume of iron = 3.6 mL
Finally, we shall determine the density of iron as follow:
Mass of Iron = 28.5 g
Volume of iron = 3.6 mL
Density of Iron =.?
Density = mass/volume
Density = 28.5/3.6
Density = 7.92 g/mL
Therefore, the density of the iron is 7.92 g/mL
