what is the molarity of a solution of KNO3(molecular mass=101) that contains 404 grams of KNO3 in 2.00 liters of solution?

A. 1.00M
b. 2.00M
c. 0.500M
d. 4.00M

The definition of molarity is #mols/Liter of solution. Convert 404 g KNO3 to mols (mols = g/molar mass) and plug into the definition.

is it B?

You are right again.

1 answer

The answer is B. 2.00M
