MHT CET Chemistry question
Two solutions of a substance (non-electrolyte) are mixed in the following manner. 480 mL of 1.5 of I solution with 520 mL of 1.2 of II solution. The molarity of final solution is:
Answer: (C)
Solution
Moles = 0.48 × 1.5 + 0.52 × 1.2 = 0.72 + 0.624 = 1.344 mol in 1.000 L, so M = 1.344 M; 1.20 M and 1.50 M are
