Dexter is testing whether an antique coin is made of pure gold. If the coin is pure
gold, it will have a density of 19.3 cm³.

.
To determine the mass of the coin, he weighs it on a scale. The coin has a
mass of 48.25 g.
To determine the volume of the coin, he uses displacement. The amount of
water displaced, or moved, by an object is the object's volume. Dexter fills a
beaker to the 100 mL mark. He places the coin inside the beaker, and the
water rises to the 102.5 mL mark.
Remember 1 mL = 1 cm³
1) What is amount of water was displaced?
2) What is the volume of the coin?
3) How do you find the density of something?
4) What is the density of Dexter’s coin?
