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. 3.
