Answer:
There are 2 Hydrogen molecules in H2O
Explanation:
if you look at the symbol for Hydrogen (H) you see that there is a number beside it, to the right. That number shows how many molecules there are of that element.
(Sidenote: If there is no number there is only one molecule)
Hope this helped :)
There are 2per molecules But the question is asking for 2 molecules of it so 2x2= 4... 4 is the answer!
