Alright.. ive been working on a few questions like this one for almost 10 hours now. I may seem stupid for not even knowing where to start... but... im lost. Help please!
Heres the question:      

A silver nitrate solution contains 15.15 g of primary standard AgNO3 in 1.00 L. What volume (in mL) of the silver nitrate solution will be needed to react with 303.1 mg of BaBr2?

I found the concentration of AgNo3 but i dont know where to go from there.

I found out how to do it.
