... Only one of these values will be possible. Looking back at our data, we started with only 4.0 mol/L of H2 . If we subtract 4.7 mol/L, we will get a negative value for concentration, which is impossible. Therefore, x=4.7 is not a realistic answer, so x=1.9 mol/L. Substitute 'x =1.9 mol/L' back up int ...
