Question- A sample of Rubidium carbonate, weighing 7.00g requires 2.20g of hydrogen chloride gas to completely decompose to water, rubidium chloride, and carbon dioxide gas. The total mass of water and rubidium chloride formed is 7.90g and no hydrogen chloride or rubidium carbonate remains. According to the law of conservation of mass, what mass of carbon dioxide must have been formed?
