Question

What is the molarity of a KCl solution if there are 59.0 grams of KCl dissolved in water to make 2.0 liters of solution?

Answer 1

Answer:0.40 M

Step-by-step explanation:

M = moles/L

moles = 59.0 / 74( molar mass from the Periodic table for KCl) =0.797 moles

M=0.797/2 = 0.3986 = 0.40 M
