Question details

Problem 3.29 Mixing and Volume Additivity A mixture of methanol (methyl alcohol) and water contains 20.00 % water by mass. Ideal Specific Gravity Correct. The specific gravity of water at 20°C is about 0.9982; the specific gravity of methanol at 20°C is about 0.7917. 0.7933 Assuming volume additivity of the components, estimate the specific gravity of the mixture at 20°C, SG- What volume of this mixture is required to provide 500.0 mol of methanol? liters SHOW HINT SHOw SOLUTION LINK TO TEXTActual Specific Gravity Your answer is partially correct. Try again. Repeat part (a) with the additional information that the specific gravity of the mixture at 20°C is 0.8469 (making it unnecessary to assume volume additivity) What is the real volume of the mixture required to provide 500.0 mol methanol? liters What percentage error results from the volume-additivity assumption? 6.75 SHOW HINT Attempts: 2 of 4 used
