3g of a hydrocarbon on combustion in excess of oxygen produces `8.8 g" of "CO_(2)" and "5.4 g` of `H_(2)O`. The data illustrates the law of :

A

conservation of mass

B

multiple proporations

C

constant proportions

D

reciprocal proportions

Text Solution

Verified by Experts

The correct Answer is:
A
Mass of carbon in 8.8 g `CO_(2)=(12)/(44)xx8.8=2.4 g`, Mass of hydrogen is `5.4 g H_(2)O=(2)/(18)xx5.4=0.6 g`
Total mass of `(C+H)=2.4+0.6=3.0 g`.
