Document Summary
38. 7 g x (1 mol / 12. 01 g) = 3. 22 mol c. 9. 7 g x ( 1 mol / 1. 008 g) = 9. 62 mol h. 51. 6 g x (1 mol / 16. 00 g) = 3. 23 mol o. 12. 01 + (3 x 1. 008) + 16. 00 = 31. 02 g/mol. (62. 1 g/mol / 31. 02 g/mol) = 2. (62. 1g eth / 1 mol eth) x (0. 387 g c / 1g eth) x (1 mol c / 12. 01 g c) 2 mol c / 1 mol eth. (62. 1 g eth / 1 mol eth) x (0. 097 g h / 1g eth) x (1 mol h / 1. 008 g h) 2 h2(g) + o2 (g) 2h2o(l) In a normal chemical reaction (non-nuclear) atoms are neither created nor destroyed. An equal number of atoms of each type are found on both sides of the equation. Stoichiometry - the quantitative relationship between products and reactants. 2 pieces of bread + 1 piece of ham 1 sandwich.
