Chapter 3 Marathon problem

From the information below, determine the mass of substance C that will be formed if 45.0 grams of substance A reacts with 23.0 grams of substance B. (Assume that the reaction goes to completion)

a. 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 Trillion Formula Units of A have a mass of 4.26 mg.

b. 47.9 grams of substance B contains 5.36 grams of hydrogen and 42.5 grams of oxygen

c. 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 ion with a mass to charge ration of 26.

d. Substance D is the hydroxide of the metal in substance A.
