Question

Correct pair of aqueous solutions with equal osmotic pressures at same temperature.

• A. 0.1 M urea, 0.2 M sucrose
• B. 0.1 M NaCl, 0.1 M glucose
• C. $0.1MN{a}_{2}S{O}_4,0.1MKCl$
• D. 0.2 M urea, 0.1 M NaCl

Answer 1

The correct option is D 0.2 M urea, 0.1 M NaCl

$\pi =0.2\times RT$
$\pi =0.1\times 2\times RT$
