At high temperature synthesis gas will form carbon dioxide and hydrogen, and in fact this reaction is one of the ways hydrogen is made industrially.

When the mixture has come to equilibrium she determines that it contains 13. mol of carbon monoxide gas, 17. mol of water vapor and 26. mol of carbon dioxide. The engineer then adds another 20. mol of water, and allows the mixture to come to equilibrium again. Calculate the moles of hydrogen after equilibrium is reached the second time.
