Mass of the solution = 100g
Mass of glucose = 10g, Mass of water = 90 g
No. of moles of glucose = 10/180 = 0.0555mol
No. of moles of water = 90/18 = 5 mol
Molality = No. of moles of solute/Mass of solvent in kg
= 0.0555mol/0.0090kg = 0.617m
Mass of glucose = 10g, Mass of water = 90 g
No. of moles of glucose = 10/180 = 0.0555mol
No. of moles of water = 90/18 = 5 mol
Molality = No. of moles of solute/Mass of solvent in kg
= 0.0555mol/0.0090kg = 0.617m

Molality of a Solution of Glucose in Water
Given:
Percentage concentration = 10% w/w
Molar mass of glucose = 180 g/mol
Molality (m) is defined as the number of moles of solute present in 1 kg of solvent.
Step-by-Step Solution:
1. Calculate the mass of glucose present in 100 g of the solution:
Mass of glucose = 10% of 100 g = 10 g
2. Calculate the number of moles of glucose:
Number of moles of glucose = Mass of glucose / Molar mass of glucose
= 10 g / 180 g/mol
= 0.0556 mol
3. Calculate the mass of water in the solution:
Mass of water = 100 g - Mass of glucose
= 90 g
4. Calculate the molality of the solution:
Molality (m) = Number of moles of glucose / Mass of water in kg
= 0.0556 mol / 0.090 kg
= 0.617 m
Therefore, the molality of the solution of glucose in water which is 10% w/w is 0.617 m.
Answer: Option B.
Given:
Percentage concentration = 10% w/w
Molar mass of glucose = 180 g/mol
Molality (m) is defined as the number of moles of solute present in 1 kg of solvent.
Step-by-Step Solution:
1. Calculate the mass of glucose present in 100 g of the solution:
Mass of glucose = 10% of 100 g = 10 g
2. Calculate the number of moles of glucose:
Number of moles of glucose = Mass of glucose / Molar mass of glucose
= 10 g / 180 g/mol
= 0.0556 mol
3. Calculate the mass of water in the solution:
Mass of water = 100 g - Mass of glucose
= 90 g
4. Calculate the molality of the solution:
Molality (m) = Number of moles of glucose / Mass of water in kg
= 0.0556 mol / 0.090 kg
= 0.617 m
Therefore, the molality of the solution of glucose in water which is 10% w/w is 0.617 m.
Answer: Option B.
