Left Compartment Right Compartment 7 grams of Z per liter solution 4 grams of XY per liter of solution total volume = 1 liter. total volume = 1 liter Solute Z has a molecular weight of 20 (non-dissociable) Solute XY has a molecular weight of 10 (dissociates into X+ and Y-) 1. If the membrane is impermeable to all solutes, and there are 7 g/l of solute in the left compartment, what concentration of XY (g/l) in right compartment would make the solutions isotonic?
Left Compartment Right Compartment
7 grams of Z per liter solution 4 grams of XY per liter of solution
total volume = 1 liter. total volume = 1 liter
Solute Z has a molecular weight of 20 (non-dissociable)
Solute XY has a molecular weight of 10 (dissociates into X+ and Y-)
1. If the membrane is impermeable to all solutes, and there are 7 g/l of solute in the left compartment, what concentration of XY (g/l) in right compartment would make the solutions isotonic?
Osmolarity is the number of solute particles per litre of solution. When there is difference in osmolarity of two solutions, separated by semi-permeable membrane, the osmolarity of the two solutions forces water and solute molecules two make two solution isotonic i.e same concentration of solutes.
