Calculate the concentration, in mol dm–3, of a solution containing 60.0 g dm–3 of hydrogen peroxide? I do number of moles= mass/ relative molecular = 1.76 moles ( thats the correct answer) but from here wouldnt you do 1.76/ 60 = 0.0295, to get the answer ? as concentration ( moldm-3) = moles/volume?
