When 6.104 grams of a hydrocarbon, CxHy, were burned in a combustion analysis apparatus, 19.15 grams of CO2 and 7.842 grams of H2O were produced. In a separate experiment, the molar mass of the compound was found to be 28.05 g/mol. Determine the empirical formula and the molecular formula of the hydrocarbon.
A 7.797 gram sample of an organic compound
containing C, H and O is analyzed by combustion analysis and
7.623 grams of CO2 and
1.561 grams of H2O are produced.
In a separate experiment, the molar mass is found to be
90.04 g/mol. Determine the empirical formula and
the molecular formula of the organic compound.

The demand for nurses in the US between 2000 and 2015 is estimated to be D(t) = 0.7t 2 + 0.265t + 2000 thousand, where 0 ≤ t ≤ 15, and t = 0 corresponds to year 2000. The number of nurses in the US between 2000 and 2015 is estimated to be S(t) = 0.14t 2 + 0.326t + 1900 thousand, where 0 ≤ t ≤ 15, and t = 0 corresponds to year 2000.
