You add 9.3 g of iron to 28.60 mL of water and observe that the volume of iron and water together is 29.78 mL . Calculate the density of iron. Express your answer to two significant figures with the appropriate units.

density = mass / volume

mass of iron = 9.3g

volume of iron = 29.78ml - 28.00ml = 1.78 ml

density of iron = 9.3 / 1.78 = 5.22471910112 = 5.0

Explanation:

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.
