We are asked to calculate the osmotic pressure of magnesium citrate laxative solution.
We are going to do the following steps:
Step 1: Calculate the molarity of the solution
Step 2: Calculate the osmotic pressure
Magnesium citrate, Mg3(C6H5O7 )2, belongs to a class of laxatives called hyperosmotics, which are used for rapid emptying of the bowel. When a concentrated solution of magnesium citrate is consumed, it passes through the intestines, drawing water and promoting diarrhea, usually within 6 hours.
Calculate the osmotic pressure of a magnesium citrate laxative solution containing 28.0 g of magnesium citrate in 236 mL of solution at 37 oC (approximate body temperature). Assume complete dissociation of the ionic compound.
