Which of the following is the incorrect conclusion regarding the reaction:

$2{\mathrm{H}}_2\left(g\right)+{\mathrm{O}}_2\left(g\right)⟶2{\mathrm{H}}_2\mathrm{O}\left(l\right)$

 

2 mole of ${\mathrm{H}}_2\left(g\right)$ will produce 2 mole of ${\mathrm{H}}_2\mathrm{O}\left(l\right)$

16 gm of ${\mathrm{O}}_2\left(g\right)$ will produce 18 gm of ${\mathrm{H}}_2\mathrm{O}\left(l\right)$

2 litre of ${\mathrm{O}}_2\left(g\right)$ at 25° C and 1 $\mathrm{atm}$ will produce 4litre of ${\mathrm{H}}_2\mathrm{O}\left(l\right)$ at 25° C and 1 $\mathrm{atm}$

2 molecules of ${\mathrm{H}}_2\mathrm{O}\left(l\right)$ is obtained from every 3 molecules of gaseous mixture of ${\mathrm{H}}_2$ and ${\mathrm{O}}_2$.
