Document Summary

Number of moles of cl in one mole of alcl3. Mass of cl / mass of alcl3 * 100. Use to determine cl mass of any sample of alcl3. 1. 11 mol of o x 16. 00 g / 1 mole = 17. 76 g. 55. 4 g 17. 76 g = 37. 64 g. 37. 64 g / 0. 742 mol = 50. 72 g / mol. In 1 molecule of glucose, there are 6 carbon atoms. In 1 mole of glucose, there are 12 moles of hydrogen atoms. Empirical formulae can be determined from elemental analysis. Compound is decomposed into elements: convert weights to moles. Insert moles into a preliminary formula: divide all moles by the lowest number, multiply all values (if necessary) by an integer to get whole numbers. Zn 13. 74 g x (1 mol / 65. 39 g) = 0. 21 mol. P 4. 34 g x (1 mol / 30. 97 g) = 0. 14 mol. O 8. 96 g x (1 mol / 16. 00 g) = 0. 56 mol.
