A 500 mL solution contains 1.2 moles of HC1. What is the molarity of this solution?
To find the molarity of a solution, we use the formula:
Molarity = moles of solute / volume of solution (in liters)
Given that the solution contains 1.2 moles of HCl and has a volume of 500 mL, we need to convert the volume to liters:
500 mL = 500/1000 = 0.5 L
Now we can calculate the molarity:
Molarity = 1.2 moles / 0.5 L = 2.4 M
Therefore, the molarity of the solution is 2.4 M.
