I need help with these, thank you in advance

Farzad fills a 25mL volumetric flask to the line with ethylene glycol. How should the volume be reported? An ethylene glycol solution is prepared by diluting 2.000 mL of a 2.383M solution to a final volume of 50.00mL. What is the molarity of the new solution? The scatter plot below shows the mass \% ethylene glycol in solutions vs. the density of those solutions. Mass % The equation for the line of best fit shown on the scatter plot is y=0.001890x+0.9924. Use the equation of the trendline to determine the mass percent of an ethylene glycol solution with a density of 1.008g/mL. %
