1. Repeated experiments involving the combination of copper and oxygen produces a product containing large variations in percentages of copper and oxygen by weight. Is this an exception to the law of definite proportions? If not, can you propose a possible explanation for this apparent anomaly? 2. A sample of a salt was found to contain 2.83 g of calcium and 2.68 g of fluorine. a) Calculate the percent composition of calcium and fluorine in this compound. b) Using the accepted atomic weights, find the empirical formula of this compound. mordiiw abbo muis abomber mancangam to grisad sola 3. One pound of sulfur combines with one pound of oxygen to produce a gas. What is the percent by weight composition of this gas?
