Which of the following is the incorrect conclusion regarding the reaction :
`2H_2(g)+O_2(g)to2H_2O(l)`
A. 2 mole of `H_2(g)` will produce 2 moles of `H_2O` (l)
B. 16 gm of `O_2` (g) will produce 18 gm of `H_2O(l)`
C. 2 litre of `O_2`(g) at `25^@C` and 1 atm will produce 4 litre of `H_2O(l)` at `25^@C` and 1 atm
D. 2 molecules of `H_2O(l)` is obtained from every 3 molecules of gaseous mixture of `H_2` and `O_2`.
