A sulphuric acid density solution of 1.38 g/ml has a concentration of 56% w/w. Calculate the amount of moles of the existing acid in 1 litre of this solution.
so one liter has a mass of 1380 grams, and of that .56*1380 is the mass of the sulfuric acid.
Moles of acid in one liter then is .56*1389/98 moles
Molarity= molesacid/1
