What is the Mass of Carbon in Sucrose?
Sucrose, also known as table sugar, is a disaccharide composed of one molecule of glucose and one molecule of fructose. It is a white, crystalline solid that is soluble in water. The chemical formula of sucrose is C12H22O11. This means that each molecule of sucrose contains 12 carbon atoms.
The mass of one carbon atom is 12 atomic mass units (amu). Therefore, the total mass of carbon in one molecule of sucrose is 12 x 12 = 144 amu.
The molar mass of sucrose is 342.3 g/mol. This means that one mole of sucrose contains 342.3 grams of sucrose. Therefore, the mass of carbon in one mole of sucrose is 144 g/mol.
**Percentage of Carbon in Sucrose**
The percentage of carbon in sucrose can be calculated by dividing the mass of carbon in one mole of sucrose by the molar mass of sucrose and multiplying by 100%.
“`
mass of carbon in 1 mole of sucrose = 144 g/mol
molar mass of sucrose = 342.3 g/mol
percentage of carbon in sucrose = (144 g/mol / 342.3 g/mol) x 100%
percentage of carbon in sucrose = 42.06%
“`
Therefore, the percentage of carbon in sucrose is 42.06%.
