First, estimate the concentration-dependent partial molar volume of copper sulfate in
water by taking finite differences. Second, fit the data to a hyperbola and take a
derivative of the hyperbola to accurately calculate the partial molar volume of copper
sulfate in water at each concentration. Interpret the partial molar volume at infinite
dilution - what must copper sulfate be doing to the nearby water molecules?
