Question

The amount of sugar $(C_{12}{H}_{22}{O}_{11})$ required to prepare $2L$ of its $0.1M$ aqueous solution is :

• A. 68.4 g
• B. 17.1 g
• C. 34.2g
• D. 136.8 g

Answer 1

Answer: (A)

Molarity $=\frac{{\left(n\right)}_{\text{solute}}}{V_{\text{solution}}\left(\text{in}\text{lit}\right)}$
$0.1=\frac{wt./342}{2}$
$wt\left(C_{12}{H}_{22}{O}_{11}\right)=68.4\text{gram}$
