Question
A student weighs out a 14.4 g sample of copper(II) bromide, transfers it to a 500 mL volumetric flask, adds enough water to dissolve it and then adds water to the 500 mL tic mark.
What is the molarity of CuBr2 in the resulting solution
The answer I keep getting is completely wrong and I am unsure why.
I keep getting .229 Mol

To bad you didn't show how you got that number. I could have looked at it and found the problem.
mols CuBr2 = gams/molar mass = ?
Then M = mols/0.5L = ?
