Hello there!
In this case, since there is a 2:2 mole ratio between sodium peroxide and water according to the given reaction, it is possible to apply the following stoichiometric setup for the calculation of the required mass of water:
![m_{H_2O}=40.0gNa_O_2*\frac{1molNa_O_2}{78gNa_O_2}*\frac{2molH_2O}{2molNa_O_2} *\frac{18.02gH_2O}{1molH_2O} \\\\m_{H_2O}=9.24gH_2O](https://tex.z-dn.net/?f=m_%7BH_2O%7D%3D40.0gNa_O_2%2A%5Cfrac%7B1molNa_O_2%7D%7B78gNa_O_2%7D%2A%5Cfrac%7B2molH_2O%7D%7B2molNa_O_2%7D%20%20%2A%5Cfrac%7B18.02gH_2O%7D%7B1molH_2O%7D%20%5C%5C%5C%5Cm_%7BH_2O%7D%3D9.24gH_2O)
