STOICHIOMETRY

STOICHIOMETRY

STOICHIOMETRY. Determining Formulas. Using Stoichiometry to Determine a Formula. Burn 0.115 g of a hydrocarbon, C x H y , and produce 0.379 g of CO 2 and 0.1035 g of H 2 O . C x H y + some oxygen ---> 0.379 g CO 2 + 0.1035 g H 2 O What is the empirical formula of C x H y ?.

Empirical formula:

Empirical formula:

Empirical formula:. Hydroquinone, used as a photographic developer is 65.4% C, 5.5% H, and 29.1% O, by mass. What is the empirical formula?. If we work with 100 grams, we would have 65.4 g C, 5.5 g H and 29.1 g O. Then: Change g to moles and convert to whole numbers. 65.4 g. = 5.42 mol C.
