⚠️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 ​⚠️

Answers

Answer:

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
