3.29. A mixture of methanol (methyl alcohol) and water contains 60.0% water by mass. (a) Assuming volume additivity of the components, estimate the specific gravity of the mixture at 20°C. What volume (in liters) of this mixture is required to provide 150 mol of methanol? (b) Repeat Part (a) with the additional information that the specific gravity of the mixture at 20°C is 0.9345 (making it unnecessary to assume volume additivity). What percentage error results from the volume-additivity assumption?
