Expert Answer

Step 1

Osmotic pressure is calculated by using the equation,

Chemistry homework question answer, step 1, image 1

Step 2

Given that the molarity of Cesium sulfate solution is 0.250 M at 298 K and molarity of phosphoric acid is 0.220 M at the same temperature. Van’t Hoff factor can be defines as the number of ions formed from one molecule of the solute when 100% dissociation of solute occurs. In-order to find out the number of ions formed, the dis...
