I don't think you entered the complete problem.
Two samples of sodium chloride were decomposed into their constituent elements. One sample produced 1.78 g of sodium and 2.74 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)?
Read the problem. You don't have all of the information. I would not understand it either.
