Answer:
Hydrogen, 0,2 mol
Explanation:
= 22, 4 l/mol
V (
) = 6,72 
= 6,72 l
V (
) = 6,72 = 6,72 l
The formula is:
n = 
n () = 6,72l /22,4 l/mol = 0,3 mol
n () = 6,72l /22,4 l/mol = 0,3 mol (the same)
But from the equation we get a proportion that 1 mol () - 3 mol ()
(we have more hydrogen than is need for the reaction)
So there is excess of
We only need 
= 0,1 mol ()
0,3 mol (hydrogen quantity we have) - 0,1 mol (hydrogen quantity we need for the reaction) = 0,2 mol (excess)
