⚠️An irregular piece of iron has a mass of 78.7 grams. When placed in a graduated cylinder with 30 mL of water, the water rises to the 35 mL ⚠️

The density of the iron is: 15.74g/cm3

Explanation:

-To determine the density of something, you have to divide the mass and the vol.

-mass/volume = density or, m/v = d

-The mass of the iron is: 78.7 grams

-The volume of the iron is 5mL

In order to find the density, you have to divide:

m/v = d

78.7g ÷ 5mL = 15.74

Hope This Helps (:

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error
