Calculate the molecular formula of the compound. The empirical formula of a compound is CH 2 O. Its molecular weight is 90. About. Transcript. There are three main types of chemical formulas: empirical, molecular and structural. Empirical formulas show the simplest whole-number ratio of atoms in a compound, molecular formulas show the number of each type of atom in a molecule, and structural formulas show how the atoms in a molecule are bonded to each other. The molar amounts of carbon and hydrogen in a 100-g sample are calculated by dividing each element's mass by its molar mass: (4.3.16) 27.29gC( molC 12.01g) Coefficients for the tentative empirical formula are derived by dividing each molar amount by the lesser of the two: 2.272molC 2.272 = 1. 4.544molO 2.272 = 2.
An empirical formula tells us the relative ratios of different atoms in a compound. The ratios hold true on the molar level as well. Thus, H 2 O is composed of two atoms of hydrogen and 1 atom of oxygen. Likewise, 1.0 mole of H2O is composed of 2.0 moles of hydrogen and 1.0 mole of oxygen.
This means the formula mass of vitamin C is 88.0. Compare the formula mass (88.0) to the approximate molecular mass (180). The molecular mass is twice the formula mass (180/88 = 2.0), so the simplest formula must be multiplied by 2 to get the molecular formula: molecular formula vitamin C = 2 x C 3 H 4 O 3 = C 6 H 8 O 6. Answer.
The empirical formula is therefore CH 2. The molecular weight corresponding to the empirical formula is. 12.01 + 2 × 1.008 = 14.03.
