Consider NaCl produced in the equation: FeCl3+ NaOH → Fe(OH)3 + NaCl 175.5g of NaCl was dissolved in water to make a liter of solution, the molarity would be:
Correct answer: B. 3 M
- A. 0.1 M
- B. 3 M
- C. 8 M
- D. 12 M
- E. 16 M
Explanation
Molarity = number of moles/volume in dm3 or liters 175.5 g make up 3 moles of NaCl 175.5/58.5 = 3 mol That means 3 mole of NaCl is dissolved in 1 liter of solution that makes the NaCl solution 3M.
