for example:
How do I find the coefficient of water (H2O)
from the balanced equation >>>    N2O5 (g) + H2O (l) ®  HNO3 (aq)

another example:
Find the coefficient of H3PO4
from the balanced equation >>>    H3PO4 (aq) + NaOH (aq) ®  Na3PO4 (aq) + H2O (l)

Step by step please. Thanks
I still don't get how NAOH, the coefficient is 3

whattttttttttt?Neutral FaceNeutral FaceNeutral Face?? how???

when there is no coefficient given we assume it to be 1

for the first example
to to make it balanced it would have to be N2O5 + H2O -> 2HNO3
the coefficient of water is 1, the coefficient of HNO3 would be 2 and also 1 for N2O5

another example:
H3PO4 + 3NaOH -> Na3PO4 + 3H2O

so the coefficient of H3PO4 is 1, coefficient of NaOH is 3 etc
