Question
Hydrogen and oxygen respectively combine together in the ratio of 1:8 by mass to form water. does this mean that if i add 1g of hydrogen and 8 g of oxygen into a bowl, water will be formed ?

Solution
Hydrogen and oxygen combined in 1 : 8 ratio to give water,
H2 + O2 ----> H2O
We know that 1 mole of H2 molecule contains = 2g
1 mole of O2 molecule contain = 16g
So, if we add 1g of H2 and 8g of O2 , water will not be formed. It can be formed only when we combine hydrogen and oxygen having a mass equal to its atomic mass.
So if we take 2 g of H2 and 16g of O2 , water will be formed.
