Calculate the number of moles of h gas
that should be burnt to produce 10 moles
of water
​

Answer 1

Answer:

Use the mass of the hydrogen gas to calculate the gas moles directly; divide the hydrogen weight by its molar mass of 2 g/mole. For example, 250 grams (g) of the hydrogen gas corresponds to 250 g / 2 g/mole = 125 moles.

How many moles of water are produced when 6.0 moles of hydrogen gas react with 2.5 moles of oxygen gas? Balanced equation: 2H2 + O2 → 2H2O. 2.5 moles of water. 3.0 moles of water.
