Empirical Formulas from Analyses (Section)
Propenoic acid is a reactive organic liquid used in the manufacture of plastics, coatings, and adhesives. An unlabeled container is thought to contain this acid. A 0.2033-g sample is combusted in an apparatus such as that shown in Figure 3.14. The gain in mass of the H2O absorber is 0.102 g, whereas that of the CO2 absorber is 0.374 g. What is the empirical formula of propenoic acid?

If we get them wrong, the consequences can be disastrous. - December 11, 1998: NASA launched the Mars Climate Orbiter, the first weather satellite for a planet other than Earth. The orbiter entered Mars’s orbit too low and disintegrated. This cost the US $125 million. - Engineers intended for the Orbiter to orbit at 226 km but entered within 57 km of the planet’s surface. The units on the system were in metric units (N/s) but the engin
