a volumetric flask made of pyrex is calibrated at 20°c. if it is filled to 100ml with 35°c acetone.
what us the volume of the acetone when it cools to 20°c and how significant is the change in the volume of the flask.

how many glasses of cola each to be filled with 150 cu. cm of the liquid can be made from 5 family size bottle of cola each containing 1.5 liters?
Suppose we want to charge a flask with 1.9 g of sugar. We put the empty flask on a balance and it is determined to weigh 170 g. Enter the weight we would expect to see on the balance when we're done adding the sugar.
A flask weights 46.8 g when it is empty and 121.6 g when filled with water. When the same flask is filled with another liquid, the mass is 91.2 g. What is the density of the second liquid?
