Two samples of sodium chloride were decomposed into their constituent elements. One sample produced 2.84 g of sodium and 4.37 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)?
4.17 g of sodium and 3.75 g of chlorine
4.17 g of sodium and 6.42 g of chlorine
4.17 g of sodium and 1.05 g of chlorine
4.17 g of sodium and 12.1 g of chlorine
