Question

How many grams of NaI would be used to produce a 2.0 M solution with a volume of 10.00 L?

Answer 1

the molarity formula: \(Molarity=\dfrac{n}{L}=\dfrac{\dfrac{m}{MW}}{L}=\dfrac{m}{L*MW}\)

MW=molar mass
m=mass
L=liters of solution
n=moles

Answer 2

i'll even rearrange it for ya, m=M*MW*L

M= molarity
