Question

An aqueous solution of glucose is $10$% (w/v). The volume in which $1$ mole of glucose is dissolved, will be:

• A. $180$ L
• B. $91$ L
• C. $0.91$ L
• D. $1.8$ L

Answer 1

The correct option is D $1.8$ L

10% glucose solution means $10g=\frac{10}{180}$

moles are present in 100cc i.e., 0.1 L

Hence, 1 mole of glucose will present in $=\frac{(0.1\times 180)}{10}=1.8L$
