Experiment Four Questions
1. I would apply the equation: Density= Mass/Volume. I would first
measure the weight of a graduated cylinder and then pour 50 mL of my
unknown into the graduated cylinder. I would then measure the mass of
the graduated cylinder with the unknown. I could then find the mass of the
50 mL of my unknown by calculating the difference in mass between the
graduated cylinder and the graduated cylinder with the unknown. After
that, I could calculate the density of the unknown by dividing my
calculated mass by the volume (50 mL).
2. The thermometer was not placed directly in the liquid when measuring the
boiling point because of the convection currents within the boiling liquid.
This means that the bulb of the thermometer would be in contact with
slightly cooler liquid that the actual boiling point. The temperature of the
vapor is more accurate because of latent heat of vaporization. This ensures
that the vapor temperature is at the boiling point.
