ART101 Lecture 3: The Power of Composition in Photography

Elemental analysis is an old technique in which a compound is combusted and the CO_2 and H_2 O evolved is collected and measured. From this procedure, a % composition of carbon and hydrogen can be measured and % composition can be deduced by assuming the remaining mass is oxygen (if nitrogen is not present). Determine the empirical formula and draw a possible structure for a organic compound with the elemental composition of 62% C, 10% H and 28% oxygen than forms a silver mirror in a Tollens test.
