A mineral sample has a mass of 35 g. When it is dropped into a graduated cylinder with 25mL of water, the volume of the water rises to 35 mL. Using this data, determine the density of the sample.

Explanation:

The density of an object is the mass per unit volume, so the formula is:

We know the mass of the mineral sample is 35 grams.

We have to calculate the volume. The volume was found using water displacement. An amount of water was put in a graduated cylinder, then the object was dropped in. The volume is the difference between the final water level and the initial water level.

Now we know the mass and volume of the mineral sample.

Substitute the values into the formula.

Divide.

The density of the mineral sample is 3.5 grams per milliliter.
