Problem on Mass Percentage
« on: October 11, 2006, 10:42:52 PM »
Hi, I'm just having trouble with this question:

A piece of 4.824 g metallic alloy compounded of only Pb and Sb, is quantitatively converted into a 5.599 g mixture of the oxides PbO2 and Sb2O4.  What is the mass percentag of antimony in the alloy?

Wride down balanced reactions separsately, set system of two equation and solve it.
Note! Sb2O4 is a wrong formula
