Question

The strength of the aqueous solution of soda ash is specified as 12 percentage Na2O by weight . express the weight percent of soda ash​

Answer 1

Answer:

The % of Na2O in NaOH = 0.775 x 100 % = 77.5 %

2) The % of Na2O in Na2SiO3 = 0.508 x 100 % = 50.8 %

So if you have 10% Na2SiO3 with 90% NaOH, the % of Na2O in this mixture = (10.0 % x 0.508) + (90.0 % x 0.775) = 0.0508 % + 0.698 % = 0.748 x 100 % = 74.8 %

But if you have 10% NaOH and 90% Na2SiO3, the % of Na2O in this mixture = (10.0 % x 0.775 + (90.0 % x 0.508) = 0.0775 %+ 0.457 % = 0.535 x 100 % =53.5
