How many atoms of oxygen in 89.2 g of aspartame

Answer and Explanation:

Molecular formula if aspartame is C14H18N2O5. Its molar mass is ~294 g/mol.

Firstly we need to calculate moles of aspartame. This can be done by converting 89.2 grams into moles,

89.2 g / 294 g/mol = 0.303 moles of aspartame

Each mole of aspartame has 5 moles of oxygen. So, we will have 1.517 moles of O in 89.2 grams of aspartame (5 x 0.303).

Finally, we can calculate the number of O atoms by multiplying with avogadro's number

= 1.517 mol X 6.02 X 10^23

= 9.13 X 10^23 oxygen atoms.

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).
