Question

One molecule of ozone, O3, contains three oxygen atoms. Similarly, 1 mole of ozone contains 3 moles of oxygen atoms. We can use this mole ratio to create two conversion factors: 3 moles O1 mole O3 and 1 mole O33 moles O Here's how to find the number of moles of oxygen atoms in 2 moles of ozone: 2 moles O3×3 moles O1 mole O3= 6 moles O

Part A Calculate the number of moles of aluminum, sulfur, and oxygen atoms in 4.00 moles of aluminum sulfate, Al2(SO4)3. Express the number of moles of Al, S, and O atoms numerically, separated by commas. View Available Hint(s) moles of Al, S, O= Part B Calculate the number of moles of magnesium, chlorine, and oxygen atoms in 6.30 moles of magnesium perchlorate, Mg(ClO4)2. Express the number of moles of Mg, Cl, and O atoms numerically, separated by commas. View Available Hint(s) moles of Mg, Cl, O = Part C A sample of propane, C3H8, contains 14.9 moles of carbon atoms. How many total moles of atoms does the sample contain? Express the total number of moles of carbon and hydrogen numerically.
