Problem

Two samples of sodium chloride were decomposed into their constituent elements. One sample produced 2.94 g of sodium and 4.53 g of chlorine. Which of the following could be the results of the decomposition of the other sample, being consistent with the law of constant composition (also called the law of definite proportions or law of definite composition)? 

a. 5.90 g of sodium and 3.54 g of chlorine 

b. 5.90 g of sodium and 1.47 g of chlorine

c. 5.90 g of sodium and 14.8 g of chlorine 

d. 5.90 g of sodium and 9.09 g of chlorine


Solution

We’re being asked what would be the result of the decomposition of a NaCl sample, being consistent with the law of constant composition or law of definite proportions.

Given:

NaCl Sample → 2.94 g of Na: 4.53 g of Cl

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.
