Question

An aqueous solution of glucose is $10\%$ in strength. The volume in which $1 \,g$ mole of it is dissolved will be

• A. 18 L
• B. 9L
• C. 0.9 L
• D. 1.8 L

Answer 1

Answer: (D)

1.8 L

Answer 2

$10 \%$ glucose solution means $10 \,g$ $=\frac{10}{180}$ mole in $100 \,cc$ ie, $0.1 \,L$ Hence, $1$ mole of glucose will present in $=\frac{0.1 \times 180}{10}=1.8\, L$
