Calculate the molarity of a solution if 300.0 mL of it contains 16.8 g of KNO3.
[Use formula weight: KNO3, 101.11 amu]....Question do I need to convert 300.0 mL to L? My initial set up looks like this: (16.8g/101.11amu)/300.0 mL my answer turns out to be 0.000553852....however the correct answer is 0.533M...thanks a billion!
