3.2 Determining Empirical and Molecular Formulas

The C-to-N and H-to-N molar ratios are adequately close to whole numbers, and so the empirical formula is C 5 H 7 N. The empirical formula mass for this compound is therefore 81.13 amu/formula unit, or 81.13 g/mol formula unit.

      The C-to-N and H-to-N molar ratios are adequately close to whole numbers, and so the empirical formula is C 5 H 7 N. The empirical formula mass for this compound is therefore 81.13 amu/formula unit, or 81.13 g/mol formula unit. We calculate the molar mass for nicotine from the given mass and molar amount of compound: Determining Empirical and Molecular FormulasJust as in Example 6, it is reasonable to assume that such small deviations from integral values are due to minor experimental errors, so round to the nearest integer. The empirical formula of caffeine is thus C 4 H 5 N 2 O. B The molecular formula of caffeine could be C 4 H 5 N 2 O, but it could also be any integral multiple of this. To Determining an empirical formula from percent composition let's say that we have some type of a container that has some type of mystery molecule in it so that's my mystery molecule there and we're able to measure the composition of the mystery molecule by mass we're able to see that it is 73 percent by mass mercury and by mass it is 27 percent chlorine so the remainder is chlorine by mass so pause this video and see if you can come up with what look
