Problem: Two samples of carbon monoxide are decomposed into their constituent elements. One sample produces 17.2 g of oxygen and 12.9 g of carbon, and the other sample produces 10.5 g of oxygen and 7.88 g of carbon. Which pair of ratios accurately demonstrates that the results are consistent with the law of definite proportions?

FREE Expert Solution

Given:

Sample 1 → produces 17.2 g of oxygen and 12.9 g of carbon

 Sample 2 → produces 10.5 g of oxygen and 7.88 g of carbon

According to the Law of Definite Proportions, all samples of a compound, no matter on their origin or preparation has the same ratio in terms of their elements.
