Answer

Explanation:

Step1: Calculate volume of iron

The volume of iron is equal to the change in water - level. So, $V = 49.10\ mL−45.50\ mL = 3.60\ mL$.

Step2: Calculate density of iron

The density formula is $\rho=\frac{m}{V}$, where $m = 28.5\ g$ and $V = 3.60\ mL$. Then $\rho=\frac{28.5\ g}{3.60\ mL}\approx7.92\ g/mL$.

Answer:

C. 7.92 g/mL
