Calculate the molarity of 2.05 L of a solution containing 1.51 g of dissolved KBr
Find the g/mol for KBr
1.51g x 1mol/g/mol of KBr
you should've gtt the answer for the mol
the formula for molarity is M = mol/L
plug the mol answer that you just found and divided by 2.05L
Then you should;ve got the answer for molarity
