If 0.8000 g of a mineral yields 0.2400 g of NaCl + KCl, and this mixture contains 58.00% of Cl, what is the percentage of Na2O and K2O in the mineral?
I already tried solving it and I got 12.69% Na2O and 3.84% K2O. However, I checked the answer key and the answers there are twice my answers (25.36% and 7.69%). I didn't know where did I got wrong. Please help me :(
I solved it by getting wight of Cl = 0.1392 g. Then I got weight of NaCl and KCl using 2 equations. Then I got the percentage by dividing the weights by 0.8 g, afterwards multiplied to 100.
