The isomer having Z specification from around dual connector as well as the chiral center S structure is:

An 'H' atom has been at the level of 3rd carbon, and we need to change its configuration, through 'R' to 'S' by CIP notation (under contrast to -OH group).
The answer
the general for of the equation of reaction is
N2 + 3 H2 ------------ 2NH3
1mol 3mole 2 mole
nH2 nNH3
(nX means number of mole of X)
according to the law of proportion
3 / nH2 = 2 / nNH3 (E)
nNH3 = m NH3 / 17.03 , and m NH3 = <span>0.575 g
consequently </span>nNH3 = 0.575 g / 17.03 = 0.03 mol
by considering (E) 3 / nH2 = 2 / 0.03 = 66.66, and nH2 = 3 / 66.66 =0.045
finally we can write
mH2 = nH2 x 2.0158 =0.045 x 2.0158 = 0.09 g
