balance the following equations and write an equation for the mole to mole relationship and the mass relationship

Question

a. Na + H2O > NaOH + H2

b. HCl + KOH > KCl + H2O

Answer 1

2Na + 2H2O > 2NaOH + H2
2 mols Na = 2 mols H2O = 2 mols NaOH = 1 mol H2.
You can plug in the masses.

The second one is done the same way.

Answer 2

2Na + 2H2O > 2NaOH + H2

How do I plug in the masses. The question is find the mass relationship
