Question

26. 8 g of ammonium chloride is dissolved in water to make a 0. 25 L solution. What is the molarity of the solution?

Answer 1

Answer: 0.5 M

Step-by-step explanation:

Ammonium chloride has a gram formula mass of 53.49 g/mol, so 26.8 grams of ammonium chloride is 26.8/53.49 = 0.501 mol.

So since molarity = (moles of solute)/(liters of solution), the answer is 0.501 / 0.25 = 0.5 M
