Moles of Co2= 22/ 44



Given, Moles of CO2 =Moles of H2


Hence, 

Moles of H2= (22/44)×2

Ans = 1 mole

Answer 2

Answer:

1 mole of CO2 = 12 + (16  2) = 44 g

  44 g CO2 = 1 mole

22 g CO2 = 0.5 mole

It means 0.5 mole of CO2will have same number of molecules as in 0.5 mole of H2.

1 mole of H2 = 2 g

 0.5 mole of H2 = 1 g

1 gram of hydrogen will have  the same number of molecules as present in 22 grams of carbon dioxide.
