Answer to Question #298206 in General Chemistry for chem

Question

How many moles of H₂O will be produced from 2.9 grams of HCl?

Answer 1

It actually depends on the reaction that takes place. But, in general, assuming that hydrogen atoms of HCl are the only ones to be converted to H₂O, the reaction will look like

X + 2HCl --> Y + H₂O

$n(H_2O)=2.9\ g(HCl)\times\frac{1\ mol(HCl)}{36.46\ g(HCl)}\times\frac{1\ mol(H_2O)}{2\ mol(HCl)}=0.040\ mol$

Again, this is just the possible scenario. There is not enough information to solve the problem precisely.
