Question

An 8.00-gram sampleyields 1.64grams of Zinc when the compound is decomposed. What is the compound?
Are you positive you posted ALL of the information? I can conclude from the data this much but that's all.
ZnX ==> Zn + X
8.00 => 1.64 + 6.36

%Zn = *1.64/8.00)*100 = 20.5%
So %X = 79.5%
but I have no idea at all what X is.
