A) 58.5
B) less than 58.5
C) more than 58.5
D) unpredicitable
Correct Answer: B
Solution :
\[\text{NaCl}\] is an ionic compound. It dissociates into ions in solution. As the osmotic pressure is a colligative property, hence observed osmotic pressure is always greater than the expected. Therefore, molecular weight is always obtained less than 58.5 (mol. wt. of\[\text{NaCl}\]), as: \[PV=\frac{W}{M}.ST\]You need to login to perform this action.
