Add about 2 ml of alcohol to the beaker and clean the inside with the tissue. Be sure the beaker is dry before you proceed. - 2). Pack the beaker with ice cubes up to, but not past, the 100 ml mark. Use the tongs to handle the ice--do not use your fingers.

Zero the scale and weigh the beaker to highest accuracy. Note the weight. - 4). Place the beaker on the hotplate and apply low heat until the ice has just melted. Remove the beaker immediately.

Weigh the cylinder and note the weight. - 6). Pour the water into the cylinder, taking care that none remains in the beaker. Wait about a half-hour, or until the water is at room temperature.
- 7). Raise the cylinder to place the water mark directly in front of your best-trained eye. The volume is the cylinder mark corresponding to the curved surface of the water, called the meniscus. Note the volume, which is the volume of ice.
- 8). Weigh the cylinder and note the weight. Subtract the empty cylinder weight to arrive at the weight of ice, and note the result.
- 9). Calculate the density of ice using the following formula:
Density of ice = weight of ice/volume of ice.
The result is expressed in grams per ml. For most practical purposes, this is equivalent to grams per cubic centimeter.
