Webuse .7504g and subtract the amount of grams of C and H to get O. Multiply the amount of O in g by (1 mol of O/16.00g) to get the amount of moles. Then make a formula divide by the smallest number and multiply to achieve smallest whole number. A compound is 80.0% carbon and 20.0% hydrogen by mass.
WebCFCs were first synthesized in 1928 by Thomas Midgley Jr of General Motors, as safer chemicals for refrigerators used in large commercial applications (Midgley and Henne, 1930).
