Question

Which of the following aqueous solutions is more concentrated (Assume the density of the solution as 1g/ml)

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

Answer 1

The correct option is A 1 M Glucose

$1m$ glucose
No. of moles of glucose = $1=180g$
Mass of solvent in kg = $1$
$\therefore$ Mass of solvent = $1000+180g$
$=1180g$
$\Rightarrow$ Volume of solution $=\frac{1180}{1}=1180ml$
$=1.18L$
$\therefore \text{concentration}=\frac{1}{1.18}M$
$=1M$
$\therefore 1M$ Glucose is most concentrated.
