- 1). Place the graduated cylinder on the balance and tare the balance. If the balance does not have a tare function, write down the mass of the graduated cylinder.
- 2). Remove the graduated cylinder and add exactly 1 milliliter of water to it.
- 3). Set the graduate cylinder with 1 ml of water on the balance and read the mass. If the balance was tared, the mass is equal to the density of the water. If you wrote down the mass of the graduated cylinder, subtract the mass of the graduated cylinder from the mass displayed to get the mass of the water, which is equal to the density of the water.
