Explanation:
Hello there!
In this case, according to the given equation, it turns out possible to say that the reaction with barium chloride proceeds with sodium sulfate only, which means we can calculate the mass of sodium in the sample by using the following procedure:
Whereas the mass of zinc is calculated as follows:
Thus, the percent sodium by mass would be:
