Question

calculate the concentration of aqua solution of glucose obtained by dissolving 10 gram of glucose in 1000 gram of water​

Answer 1

Answer:

Explanation:

Molality is given by the no of moles of solute present in 1 kg of solvent.

m = moles of glucose/mass of water

Moles of glucose= mass given/ molar mass

Moles= 18/180= 0.1 mole

Molality= 0.1 × 1000/1000= 0.1

So the concentration of glucose present is 0.1 m
