Part 1. Percent Recovery.. A student starts the recrystallization of benzoic acid experiment with 0.592 g of crude material. After recrystallization they recover a sample of benzoic acid weighing 0.305 g of pure benzoic acid. The molecular weight of benzoic acid is 122.1 g/mol. Calculate the percent recovery of benzoic acid. Please show your work and round your answer to the nearest whole number.

Which variable would be on the y-axis (and why)?c. Would you expect the slope to be positive or negative (and Why)? 2) Contrast and compare interpolation with extrapolation. Which is “safer” to use and why?3) Look up how “the best fit straight line” is constructed. The term “Least squares” should be in your explanation.4) If I plot some data and end up with a r2 of (-) 0.99, is my plot useless? Explain.
