Question

What is the molality of a solution composed of 342 moles of sugar (C12H22O11) dissolved in 171 kilograms of water (H20)?

Answer 1

Answer:

2 mol/kg

Explanation:

moles of solute(C12H22O11) is 342 moles

mass of solvent(H2O) in kg 171

molality of solution is,

m= moles of solute/mass of solvent (kg)

m= 342/ 171

m= 2 mol/kg
