The molar mass of the unknown substance is 256.6 g/mol.
What is the molar mass of sucrose?
The molar mass of sucrose C12H22011 is 342 g/mol.
A 2% sucrose solution is isotonic with 1.5% solution of an unknown substance.
Molar mass of sucrose = Molar mass of unknown substance.
2% × 1000/342 = 1.5% × 1000/x
x = 342 × 1.5/2
x = 256.5 g/ mol
Therefore, the molar mass of the unknown substance is 256.6 g/mol.
