Question

A 5.00g sample of compound is dissolved in enough water to form 100.0ml of solution. Thissolution has an osmotic pressure of 25torr . If it is assumed that each molecule of the solute dissociate into two particles in the solvent, what is the molar mass of this solute?​

Answer 1

See the above attachment then at last write this

Molar mass= 5.00g×2×0.082056 L.atm/mol.k × (25+273.15k)× 1/25.0 torr× 760torr/1atm×1/0.100L= 7.44×10^4 g/mol Ans!!
