Suppose you weigh the unknown substance on an electronic balance and find it has a mass of 445 grams. Analyzing the products of decomposition, you find that the masses of the elements in the sample are 232 grams of carbon, 58 grams of hydrogen, and 155 grams of oxygen. Finally, through further experimentation, you determine that the molar mass of the compound is 46.07 grams/mole. Calculate the amount, in moles, of each component element in your substance. Use the periodic table to help you find the necessary molar masses.
