same beaker used for the filtrate. The filtrate is now diluted to 50 ml. An ordinary graduate will do very well for the dilution. The sample should be run soon after dilution, since standing for more than an hour will cause some additional silver salts to precipitate. The solution is run in 10-mm. Corex glass cells. No. of grams per liter = Ko CALCULATION.Using the formula density (the reciprocal of the constant usually obtained when the BeerLambert law applies), we have from the third column of Table I, 7.5 oppobite 305 mp: o,478 = 15.7. Then (KOX 10) X density = grams per liter of K N 0 3 or 157 X D = grams per liter of I
