Omotic Pressure is a technique used to find the length of a polymer using its Molar Mass. If a 32.25 mg sample of PVC (polyvinyl chloride) is dissolved in benzene to 25.00 mL total solution at 30.00 oC, its osmotic pressure is 7.268 mm Hg. What is the Molar mass of the PVC?​​ = i MRT​760 mm Hg = 1.00 atm​R = 0.08206 L-atm / mol K

Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.
