The balanced Chemical equation is :

2H2  + O2 ----->2H20

Molar mass of H2=2g
Molar mass of O2=32g
Molar mass of H2O=36g

∴ 4g Of hydrogen reacts with 32g of oxygen to produce 36g of water.
1 mole of water=18 grams
2 moles of water=36 grams

In the question its given as :
5g H2 + 32g of O2 ----> how many moles of water

Answer would be:
 
2 moles of water [36 g] because O2 available is 32g and it acts as limiting reagent/reactant and hydrogen is excess reactant.
