Question

1. A 10g sample of a sugar (Kp = 5) that is dissolved in 20 mL water with 20 mL of ether available to extract the sugar. How much sugar will be extracted with a single extraction, using a 20 mL portion of ether? How much sugar would be extracted after two, successive extractions with 10 mL portions of ether? Which process is more efficient?
2. Adipic acid prefers to be in a organic or aqueous layer?

I would do this but you must do the work. You must solve two simultaneous equation unless I've missed the boat.
Let X = grams glucose
and Y = grams sucrose.
========================
pi = osmotic pressure = MRT
You know pi, R, and T, solve for M
Molarity = moles x L
You know L, solve for moles.
Here are the two equations.
X + Y = 1.10
(X/molar mass glucose) + (Y/molar mass sucrose) = moles.
Solve for X and Y, then you can determine percent of each.
