In this experiment, you will be graphing the relationship between mass and volume. You will be placing the volume on the x-axis, and the mass on the y-axis. Graphing the data in this way will
cause the slope of the linear regression to have a special meaning. What is the meaning of the
slope in this case?
The slope will tell us the volume when there is no mass
a
The slope will equal the average density of the solution
The slope will tell us the mass when there is no volume
a
The slope will tell us the inverse of the density of the solution.

One way in which the useful metal copper is produced is by dissolving the mineral azurite, which contains copper(ii) carbonate, in concentrated sulfuric acid. the sulfuric acid reacts with the copper(ii) carbonate to produce a blue solution of copper(ii) sulfate. scrap iron is then added to this solution, and pure copper metal precipitates out because of the following chemical reaction: (s) (aq) (s) (aq) suppose an industrial quality-control chemist analyzes a sample from a copper processing plant in the following way. he adds powdered iron to a copper(ii) sulfate sample from the plant until no more copper will precipitate. he then washes, dries, and weighs the precipitate, and finds that it has a mass of .
