Density is equal to the mass of a substance divided by its volume: density = mass of substance/volume of substance Water displacement can be used to find the volume of a solid by placing the object in a known volume of water. When the object is added to water, the measured total volume increases. This final volume is equal to the volume of the initial water plus the volume of the solid object added. To determine the volume of the...

1. A volatile organic liquid with known molecular weight is added to a vapor density flask which has a known volume. The flask is heated using a boiling water bath until all of the liquid has evaporated. After heating for an additional 1 or 2 minutes, the flask is removed from the boiling water bath, corked, and cooled using a room temperature water bath. Predict the mass of condensed vapor. Temperature of the hot water bath (ºC): 99.5 Volume of...
