Question

$234.2gm$ of sugar syrup contains $34.2gm$ of sugar. What is the molal concentration of the solution.

• A. $0.1$
• B. $0.5$
• C. $5.5$
• D. $55$

Answer 1

Answer: (B)

$0.5$

Weight of water in sugar syrup $=234.2-34.2=200gm$

Molecular weight of sugar $=342$

Molal concentration $=\frac{34.2}{342}\times \frac{1000}{200}$

Molal concentrtion $=0.5$

$\therefore$ option B is correct.
