Determine the mass of substance C that will form when 45.0 grams of substance A reacts with 23.0 grams of substance B. (Assume that the reaction between A and B goes to completion.) Substance A is a gray solid that consists of an alkaline earth metal and carbon (37.5% by mass). It reacts with substance B to produce substances C and D. Forty million trillion formula units of A have a mass of 4.26 milligrams. 47.9 grams of substance B contain 5.36 grams of hydrogen and 42.5 grams of oxygen. When 10.0 grams of C is burned in excess oxygen, 33.8 grams of carbon dioxide and 6.92 grams of water are produced. A mass-spectrum of substance C shows a parent molecular ion with a mass-to-charge ratio of 26. (This means that the molar mass is some whole number multiple of 26 g/mole). Substance D is the hydroxide of the metal in substance A.
