Consider the equation for the formation of water.


2H2 + O2 ---> 2H2O


What is the theoretical yield of H2O if 130 g of H2O is produced from 18 g of H2 and an excess of O2?

Respuesta :

The theoretical yield is 160 g H₂O.

Moles of H₂ = 18 g H₂ × (1 mol H₂/2.016 g H₂) = 8.93 mol H₂

Moles of H₂O = 8.93 mol H₂O × (2 mol H₂O/2 mol H₂) = 8.93 mol H₂O

Theoretical yield of H₂O = 8.93 mol H₂O × (18.02 g H₂O/1 mol H₂) = 160 g H₂O
