`11.2 g` of carbon reacts with 21.1 litres of oxygen at `18^(@)C` and `750 mm` of `Hg`. The cooled gases are passed through 2 litre of `2.5 N NaOH`. Determine the concetration of `NaOH` remaining in solution which is not converted to `Na_(2) CO_(3)`. Assume that `CO` does not react with `NaOH`:
a. Whatis the mole fraction of `CO` in the gases?
b. What is the concetration of `NaOH` which is not converted to `Na_(2) CO_(3)` in the remaining solution?

Answer

(i) `0.122`, (ii) `3.362,1.681`;
