An organic compound with C =40 % and H= 13.33 % and N=46.67 % Its empirical empirical formula would be. 32533006. 1.6k+. 31.4k+. 1:14. An organic compound contains carbon, hydrogen and oxygen. Its chemical analysis gave C, 38.71% and H, 9.67%. The empirical formula An unknown compound has a molar mass of 118.10 g/mol An unknown compound has a molar mass of 118.10 g/mol. Given the following mass percent composition, calculate the empirical and molecular formula. C = 40.7% H = 5.13% O = 54.2%
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: Empirical Formula - Purdue University(4.028 mol C/ 3.336) = 1.2 mol C (8.056 mol H/ 3.336) = 2.4 mol H. Use the mole ratio to write the empirical formula. The mole ratio did not turn out to be whole numbers. Since the we cannot have partial atoms in the empirical formula, a multiplication factor must be applied to get whole numbers. In this case, 5 is the factor we need.
