What is the molality of a solution of 50g of I2 (iodine) dissolved in 130 mL of propane. Propane density .49g/mol.
mols I2 = grams/molar mass
Solve for mols I2.
Use density to convert 130 mL propane to grams.
m = mols solute/kg solvent
Solve for mols I2.
Use density to convert 130 mL propane to grams.
m = mols solute/kg solvent
