Finding the volume of a flask. A student obtained a clean, dry glass-ssoppered flask. She weighed the flask and stopper on a walytic balance and found the total muss to be 33.695 g. She then filled the flask with water and okeained aa the full stoppered flask of 64356 g. From these data, and de fact tut the lempenturedtcldunn the density of water was 09978 g'cm2, find the volume of the stoppered flask a. First we need to obain the mass of the water in the flask. This is found try recogriáng that the mas of a sample is equal to the sum of the masses of its parts. For the illed stoppered flank Mass of filled stoppered naskemass of eå¥stoppered nak + mndwaer. so mass of water mass of filled flask- mass of empty flask Mass of water Many 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 is volume m volume mass density mass or Density -volume or volume densiy 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 cm Volume of water e volume of Task - Finding the density of an unknown liquid. Having obtained the volume of the flask, the student emptied the flask, dried it, and filled it with an unknown whose density she wished to determine. The mass of the stoppered flask when completely filled with liquid was 58 540 g. Find the density of the liquid. 2. g a. First we need to find the mass of the liquid by measuring by difference g= g Mass of liquid= (continued on following page)
