How do you calculate empirical formula of a combustion?

Answer 1

You might want rephrase this question.

Empirical formula are generally determined by combustion reactions. An accurate mass of hydrocarbon #C_nH_mN_nO_o# is dropped into a furnace. The combustion products. #CO_2#, #H_2O#, #NO_2# are shunted to a gas chromatograph. Their concentrations are compared to a standard, and a very accurate percentage composition with respect to #C#, #H#, #N#, may be determined.

If the molecular mass is known or has been found in a different experiment, the molecular formula of the compound is thus available. Given these percentages, an empirical formula may be calculated.

Answer 2
  1. Determine the mass of each element present in the compound from the provided data.
  2. Using the respective molar masses of each element, convert the masses to moles.
  3. Divide the moles of each element by the smallest number of moles calculated.
  4. If necessary, multiply the resulting ratios by an integer to obtain whole numbers.
  5. Write the empirical formula using the whole-number ratios obtained in the previous step. This is how to calculate the empirical formula of a compound from a combustion reaction.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
