Final answer:
When you add 253g of table sugar to a recipe, you are adding 0.738 moles of sucrose. There are 11 oxygen atoms in one mole of sucrose, so you would be adding 8.118 oxygen atoms.
Step-by-step explanation:
Table sugar, or sucrose (C12H22O11), consists of 12 carbon atoms, 22 hydrogen atoms, and 11 oxygen atoms. When you add 253g of table sugar to a recipe, you are adding molar amount of sugar. To calculate the number of oxygen atoms added, we need to determine the number of moles of sucrose and then multiply it by the number of oxygen atoms per mole. The molar mass of sucrose is 342.3 g/mol. To find the number of moles, we divide the mass of sucrose by its molar mass: Number of moles = Mass of sucrose / Molar mass of sucrose
Number of moles = 253g / 342.3 g/mol = 0.738 moles
Since there are 11 oxygen atoms in one mole of sucrose, multiplying the number of moles by the number of oxygen atoms per mole gives us: Number of oxygen atoms = Number of moles * Number of oxygen atoms per mole
Number of oxygen atoms = 0.738 moles * 11 = 8.118 oxygen atoms
