Calculate the molarity of 2.05 L of a solution containing 1.51 g of dissolved KBr

• chemistry -

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
