How to fill out chm 151ll density accuracy

How to fill out chm 151ll density accuracy:

1. Gather the necessary materials: a balance, a graduated cylinder, a beaker, and the substance whose density you want to measure.
2. Tare the balance by placing an empty container on it and pressing the "tare" button. This ensures that the weight of the container is not included in the measurement.
3. Carefully measure the mass of the substance using the balance and record the value.
4. Fill the graduated cylinder with a known volume of water and record the volume.
5. Gently add the substance to the water in the graduated cylinder, making sure it does not overflow. Take note of the new volume reading.
6. Calculate the density by dividing the mass of the substance by the change in volume.
7. Repeat the experiment multiple times to ensure accuracy and calculate the average density.
