Vedclass · Answer

(D) $10\%$ aqueous solution of glucose means $10 \, g$ of glucose is present in $100 \, mL$ of solution.The molar mass of glucose $(C_6H_{12}O_6)$ is $180 \, g/mol$.Number of moles in $100 \, mL$ solution = $\frac{10 \, g}{180 \, g/mol} = \frac{1}{18} \, mol$.This means $\frac{1}{18} \, mol$ is present in $100 \, mL$ $(0.1 \, L)$.Therefore,$1 \, mol$ of glucose will be present in volume = $\frac{0.1 \, L 	imes 1 \, mol}{1/18 \, mol} = 0.1 	imes 18 = 1.8 \, L$.
