Hydrogen and oxygen combine in the ratio of 1 : 8 by mass to form water. What mass of oxygen gas would be required to react completely with 3 g of hydrogen gas?

Dear Student


Ratio of H : O by mass in water is:
Hydrogen : Oxygen → H2O
1 : 8 = 3 : x
x = 8 × 3
∴ 24 g of oxygen gas would be required to react completely with 3 g of hydrogen gas.


Thanks
