Write the principle involved in the estimation of carbon and hydrogen.

1.	Write the principle involved in the estimation of carbon and hydrogen.Give diagram and calculation.
Answer» Solution :Principle: A known mass of an organic compound is burnt in presence of excess of oxygen and CUPRIC oxide. CARBON and Hydrogen. In the compound are converted into `CO_(2)` and `H_(2)O`. The masses of `CO_(2)` and `H_(2)O` PRODUCED is DETERMINED from which the percentage of carbon and Hydrogen are calculated. Calculation: % age of Carbon `=(12xxM_(2)xx100)/(44xxM)`, % age of Hydroen `=(2xxM_(1)xx100)/(18xxM)`
