Question

Which of the following aqueous solution is more concentrated?

(Assume that the density of the solution is $1g/ml$)

• A. $1M$ Glucose
• B. $1m$ Glucose
• C. $0.5m$ Glucose
• D. $0.5M$ Glucose

Answer 1

The correct option is A $1M$ Glucose

1 M glucose is more concentrated than 1m aqueous solution because 1M solution contains 1 mole of solute in 1 litre of solution [ where both solute and solvent are present]. This the mass of solvent [water]is less than 1000g/1litre. Whereas in 1m solution, 1 mole of solute is present in 1000g of solvent.
