2. The slopes of the lines in graph 1 can be interpreted as a useful quantity around the lab if you were working with water or one of these solutions. Explain the significance of the slope and how it might be used around the lab. Hint: look at the units and remember when a line is drawn it represents a sort of average as it places about half of the data above and below it due to random errors.

Help me out please and please check if mass of 3.0M HCl is correct

please answer in the format that it is asking for below the question.

Is their a true chemistry defeinition of what "percent by volume means?" If so, can it be described as this definition:   Volume/volume percentage (v/v percent) is a measure of the concentration of a substance in a solution. It is expressed as the ratio of the volume of the solute to the total volume of the solution multiplied by 100.
