Answered You can hire a professional tutor to get the answer.
A mixture of methanol (methyl alcohol) and water contains 70.00% water by mass.
Note: I did part (a), but I need help with part (b).
A mixture of methanol (methyl alcohol) and water contains 70.00% water by mass.
Ideal Specific Gravity
a) The specific gravity of water at 20°C is about 0.9982; the specific gravity of methanol at 20°C is about 0.7917.Assuming volume additivity of the components, the specific gravity of the mixture at 20°C is 0.92762.
The volume of this mixture required to provide 450.0 mol of methanol is 51.914.
Actual Specific Gravity
b) Repeat part (a) with the addional information that the specific gravity of the mixutre at 20°C is 0.9515 (making it unnecessary to assume volume additivity).What is the real volume of the mixture required to provide 450.0 mol methanol? (in liters)What percentage error results from the volume-additivity assumption? ( in %)
