`2H_2O rarr 2H_2+O_2`

 

Mole ratio

`H_2:O_2 = 2:1`


Molar mass in grams

`H_2 = 2`

`O_2 = 32`

 

At the medium hydrogen is as `H_2` and Oxygen is as `O_2` .

 

Amount of `H_2 ` moles in 1g of Hydrogen `= 1/2`

Amount of `O_2` formed `= 1/2xx1/2 = 0.25`

 

Mass of `O_2 = 0.25xx32 = 8g`

 

So 8g of `O_2` gas will be formed for every 1g of `H_2` .
