Respuesta :
In the balanced reaction shown, there are twice as many moles of water as oxygen. If 13.35 moles of oxygen are reacted, 26.70 moles of water is formed.
The moles of water that are produced from 13.35 mol of oxygen is 26.70 moles (answer B)
calculation
2H2 +O2→ 2H2O
The moles of H2O is calculated using mole ratio.
that is; from the balanced equation above the mole ratio of O2 :H2O is 1:2
therefore the moles of water=13.35 moles x 2/1 =26.70 moles
