Transcribed Image Text:A 0.0257 M solution of a strong electrolyte has an osmotic pressure of 1.99 atm at 328 K. What is the van't Hoff factor (i) for the unknown solute?
Expert Solution
Step 1

Given:

1) Osmotic pressure is (π)=1.99 atm

2) Temperature (T)=328 K

3) Concentration is (C)=0.0257 M = 0.0257 mol/L

4) The universal gas constant is (R) = 8.314 J/mol K = 62.4 L Torr/K mol

5) The van't Hoff factor is = (i)
