10. Draw a graph of the concentration of NaCl (x-axis) against the calculated density (y-axis) for the data in section B above. Find the straight line equation. - The graph has to be manual on graph paper, and you should draw a best-fit straight line. 11. Calculate the density of 35% NaCl from your graph.
