Aluminium oxide contains 52.9% aluminium and carbon dioxide contains 27.27% carbon. Assuming the validity of the law of reciprocal proportions , calculate the percentage of aluminium in aluminium carbide.

Explanation

From the data, it is observed that the ratio of masses of aluminium and carbon in aluminium carbide should be 3:1 or its simple multiple, Hence, percentage of aluminium in aluminium carbide `=(3)/(4)xx100=75.0`
