The molality and molarity of a solution of a glucose in water which is labelled as \(10 \%\) \((w / w)\) are respectively (density of solution \(\left.=1.2 \mathrm{~g} \mathrm{~mL}^{-1}\right)\)
- A \(0.57 \mathrm{~m}, 0.517 \mathrm{M}\)
- B \(0.67 \mathrm{~m}, 0.617 \mathrm{M}\)
- C \(0.617 \mathrm{~m}, 0.67 \mathrm{M}\)
- D \(0.517 \mathrm{~m} ; 0.57 \mathrm{M}\)
Answer & Solution
Correct Answer
(C) \(0.617 \mathrm{~m}, 0.67 \mathrm{M}\)
Step-by-step Solution
Detailed explanation
Mass by mass percentage is the mass of solute dissolved in \(100 \mathrm{~g}\) of the solution. Mass of solution \(=100 \mathrm{~g}\) Mass of glucose \(=10 \mathrm{~g}\) Mass of solvent \(=90 \mathrm{~g}\) Molar mass of glucose…
