Write an balance the equation
Na2O + H2O -> 2 NaOH
Calculate the molecular mass of Na2O and NaOH from the atomic mass from the periodic table.
Na = 23
O=16
H=1
Na2O = 23 * 2 + 16 = 62
NaOH = 23+16+1= 40
For the stoichiometry of the reaction one mole of Na2O = 62g produce two mol of NaOH = 2* 40= 80 g
120 g Na2O x 80g NaOH / 62g Na2O=
154.8 g NaOH

Answer:
The outer core is the only layer that is liquid. It is also mainly made from nickel and iron. The main job of the outer core is that it's responsible for the Earth's magnetic field. As the earth spins, the liquid inside this layer spins aswell, keeping it balanced.
