print Date REPORT SHEET: Experiment 2 Preparing Graphs 1. A series of data points are plotted on the graph to the 7 right. (a) Draw the "best" straight line through the points while not passing directly through any data point, and (b) determine the value of the intercept. Intercept 10 volune of solution (ml) To the right is a plot of the mass of solute in various volumes of a concentrated acid solution. 2. (a) Calculate the slope of the line and report the value with the correct units 20 slope 10 (b) Write the mathemati- cal equation for the straight line that relates mass of solute and volume of solution. 0 20 40 60 0 volume of solution (ml)Explanation / Answer
2. Here in this straight line which is given we can use the normal mathematical equation i.e.
y = mx + c
where, y = the Y- axis of the graph
x = the X- axis of the graph
m = slpoe of the straight line
c = intercept of the straight line
Now , comparing both the axis we get that ,
mass of the solute (g) = slope(m) * volume of the solution(mL)
Therefore, slope(m) = mass of the solute(g) / volume of the solution(mL)
i.e. Slope(m) = g/mL = Density
1. Drawing of graph without touching the data line is not possible to draw here.
