Dakota found a shiny substance she believe might be diamond. The mass of this substance was 9 grams. Her initial volume was 20ml and after placing the the substance in the graduated cylinder the volume increase to 23ml. Did she find real diamond? Hint: The density of diamonds is 3.5g/ml.

What is No, the density of her substance is 3g/ml while the density of a pure diamond is .5g/ml more.
