The density of 70.5 weight% aqueous perchloric acid is 1.67 g/ml. Recall that grams refers to grams of solution (=g HClO4+g H2O). How many grams of HCIO4 are in 1 Liter?
In addition, second part: an aqueous solution of antifreeze contains 6.067M ethylene glycol HOCH2CH2OH and has density of 1.046 g/ml. Find the mass of 1 liter of this solution and the number of grams of ethylene glycol per liter. Find molarity of ethylene glycol in this solution.
