Answer:
The answer is 2.67 g/mL
Step-by-step explanation:
The density of a substance can be found by using the formula
![density = (mass)/(volume) \\](https://img.qammunity.org/2021/formulas/chemistry/college/2qztd1zu9lpwav17leag2cjjn695yipoje.png)
From the question
mass of iron = 8 g
volume = final volume of water - initial volume of water
volume = 49 - 46 = 3 mL
We have
![density = (8)/(3) \\ = 2.666666...](https://img.qammunity.org/2021/formulas/physics/high-school/pio6ldsrhihnr2dnwjmdohm0u7kcn6oiuv.png)
We have the final answer as
2.67 g/mL
Hope this helps you
