You have a 1.0-cm3 sample of lead and a 1.0-cm3 sample of glass. You drop each in separate beakers of water. How do the volumes, of water displaced by each sample compare? Explain.

Finding the volume of a flask. A student obtained a clean, dry glass-stoppered flask. She weighed the flask and stopper on an analytical balance and found the total mass to be 34.166g. She then filled the flask with water and obtained a mass for the full stoppered flask of 68.090g. From these data, and the fact that at the temperature of the laboratory the density of water was 0.9975g/mL, find the volume of the stoppered flask. a. First we need to obtain the mass of the water in the flask. This is found by recognizing that the mass of a sample is equal to the sum of the masses of its parts. For the filled, stoppered flask: Massoffilledstopperedflask=massofemptystopperedflask+massofwater,somassofwater=massoffilledflaskmassofemptyflask Massofwater=gg=g Many mass and volume measurements in chemistry are made by the method used in la. This method is called measuring by difference, and is a very useful one. b. The density of a pure substance is equal to its mass divided by its volume: Density=massvolume or volume=massdensity The volume of the flask is equal to the volume of the water it contains. Since we know the mass and density of the water, we can find its volume and that of the flask. Make the necessary calculation. Volumeofwater=volumeofflask=mL
