Hi,
I have a solution of 150 mM of ammonium acetate in water. How do I calculate the osmolarity of this solution?
I understand that an osmole (Osmol) is 1 mol of particles that contribute to the osmotic pressure of a solution and that NaCl breaks into two particles in solution (both Na and Cl), thus giving 2 Osmols/liter. I just don't know how to do this for ammonium acetate!
From my reading online it seems ammonium acetate will disassociate into CH3COO- (aq) + NH4+ (aq), giving 2 particles in solution and thus be 2 Osmols. If this is the case the osmolarity would be 300. Is this correct?
Any help would be most welcome!
