Maple syrup is produced from sap of maple trees that is evaporated until the concentration of sugar (mostly sucrose is C12H22O11 molar mass: 342.3g = 1 mole) in the sap reaches at least 66% by weight. 1) What is the solute in this solution? How do you know? 2) What is the molality of this solution? Assume a 100 g solution. Please help with full answer and steps.

Answer #1

1)

here solute is water

because solute mass is less than the solvent mass in the solution .

here 66 g of sucrose

mass of solution = 100 g

, so mass of water = 100 - 66 = 44 g

so here water mass is less. so this is solute.

2)

mass of water = 44 g

moles of water = 44 / 18 = 2.44

mass of solvent = 66 g

molality = moles of solute / mass of solvent in kg

            = 2.44 / 0.066

molality   = 37. 0 m
