What is the concentration in molarity of a 250 mL solution made with 43.4 grams of LiBr?
Molarity = molar concentration = how many moles in
(I've used the rounded molar masses)
Molarity is defined by the following equation
So, we first need to convert
We can also convert the amount of milliliters to liters.
Now, we have the desired units, we can plug it into the molarity equation.
We can also write it as
