Question

You add 9.3 g iron to 29.40 mL of water and observe that the volume of iron and water together is 30.58 mL . Calculate the density of iron.

Answer 1

7,881 g/L

Step-by-step explanation:

Iron volume = 30.58 mL - 29.40 mL = 1.18 mL

1.18 mL / 1000 mL = 0.00118 L

Iron density = mass/volume

= 9.3g / 0.00118 L

= 7,881 g/L
