The coefficients of the substances give you the ratio of the number of moles.
The 4 before the H2O and the 5 before the HCl tell you that for every 5 moles of HCl created, 4 moles of H2O had to react.
Therefore:
can be used to find the moles of H2O that react.

Answer: The standard potential for this cell is +1.49 V at 25C.
Explanation:
As titanium has lower reduction potential, it will act as anode and tin will acts as cathode.
Using Nernst equation :
where,
F = Faraday constant = 96500 C
R = gas constant = 8.314 J/mol.K
T = room temperature =
n = number of electrons in oxidation-reduction reaction = 2
Where both are standard reduction potentials.
= standard electrode potential of the cell = 1.49 V
= emf of the cell = ?
Now put all the given values in the above equation, we get:
