MHT CET Chemistry question
200 mL of a solution contain 5.85 g dissolved sodium chloride. The concentration of the solution will be (Na = 23, Cl = 35.5)
Answer: (C)
Solution
Moles of NaCl = 5.85/58.5 = 0.1 mol, so molarity = 0.1/0.200 = 0.5 M; 1 M, 2 M and 0.25 M are not obtained. Hence the correct option is (c).
