When table sugar (sucrose, C12H22O11) is heated, it decomposes to form C and H2O.?
Write a balanced equation for the process.
How many grams of carbon are formed by the breakdown of 59.0g of sucrose?
How many grams of water are formed when 3.40g of carbon are formed?
C12H22O11 = 12C 11H2O
sucrose = 342.2979 g/mol
59.0g / 342.2979 g/mol = 0.2 mol of sucrose
(0.2 mol of sucrose)(12 mol of carbon / 1 mol of sucrose) = 2.4 mol of carbon
(2.4 mol)(12.01078 g/mol) = 28.8 g of carbon
3.40 g / 12.01078 g/mol = 0.28 mol
(0.28 mol of carbon)(11 mol of H2O / 12 mol of carbon) = 0.27mol of H2O
(0.27mol)(18.0153 g/mol) = 4.86 g of H2O
