Question
From the equation for burning of hydrogen and oxygen
\[\ce{2H2 + O2 -> 2H2O}\] (Steam)
Write down the number of mole (or moles) of steam obtained from 0.5 moles of oxygen.

Solution
\[\ce{2H2 + O2 -> 2H2O}\] (steam)
1 mole of Oxygen gives = 2 moles of steam
so, 0.5 mole oxygen will give = 2 × 0.5 = 1 mole of steam
