What is the molality of a d-mannose solution prepared by dissolving 45.0 g of d-mannose, c6h12o6, in 125.9 g of water?

The molality of 45 g of D- mannose in 125.9 g of water will be 1.985 m.

Explanation:

Molality is the number of moles of a solute in a solution per kg of solvent.

Molality =

Molecular weight of = 180.156 grams

Mass of water = 125.9 g = 0.1259 kg

Molality =

Molality = 1.985 m

The molality of a d-mannose solution prepared by dissolving 45 g of d-mannose in 125.9 g of water has the molality of 1.985 m.
