A student dissolves 12. g of sucrose C12H2011) in 200. mL of a solvent with a density of 1.11 g/mL. The student notices that the volume of the solvent does not change when the sucrose dissolves in it. Calculate the molarity and molality of the student's solution. Be sure each of your answer entries has the correct number of significant digits. molarity = 0 molality = 0 x 6 ?

A student performed a series of measurements (volume/mass) of an unknown liquid in order to determine its density. Using a graduated cylinder, the student added an amount of unknown liquid to the graduated cylinder, then recorded the mass and volume of the liquid. The student repeated the process several times, adding more liquid each time and recording the mass and volume. The student plotted the data (mass on y-axis, volume on x-axis). The resulting data table and graph looked like...
