7. A sample of a compound that contains only chlorine and oxygen reacts with excess hydrogen to produce 0.233 grams of hydrochloric acid and 0.403 grams of water. Determine the empirical formula of this compound.

ClxOy + H2 > HCl + H2O

HCl = 0.233/37 = 0.006 mol H2O = 0.403/180.02 mol

HCl = 0.006/0.022 H2O = 0.022/0.006

= 1 = 4

Cl2O4 + 5H2 > 2HCl + 4H2O

I'm think that's the answer
