Question: how many oxygen atoms would there be in 100.0 grams of sodium acetate?
Answer: How many oxygen atoms would there be in 100.0 grams of sodium acetate? Moles of sodium acetate is 100g x (1 mol Sodium Acetate/82.034g) = 1.219 mol. Moles of oxygen is 2 x 1.219mol = 2.438 mol of O. Finally, 2.438 mol x (6.02 x 10 /mol) = 1.47 x 10 oxygen atoms.
