Suppose $60 % w / w$ aqueous solution of glucose $(C_{6} H_{12} O_{6})$ and $20 % w / w$ aqueous solution of urea $(N H_{2} C O N H_{2})$ have equal molarity, then which solution has higher density:

Options:

Answer:

Solution:

Given:

$M_{1} = M_{2}$

$\frac{10 d_{1} x_{1}}{{M o l . w t .}_{1}} = \frac{10 d_{2} x_{2}}{{M o l . w t .}_{2}}$

$∴ \frac{d_{1}}{d_{2}} = \frac{x_{2}}{x_{1}} \times \frac{{M o l . w t .}_{1}_{}}{{M o l . w t .}_{2}} = \frac{20}{60} \times \frac{180}{60} = \frac{1}{1}$

Thus, $d_{1} = d_{2}$ Here $x_{1}, x_{2}$ are percentage weights.
