Calculating Percent Composition Mrs. Page 10 th Chemistry

What is the percentage of the various elements in Sodium Carbonate, Na 2 CO 3 Find the molar mass of the compound by adding up the masses of each atom in the compound. Calculate the mass due to the component in the compound you are for which you are solving by adding up the mass of these atoms. Divide the mass due to the component by the total molar mass of the compound and multiply by 100.

What is the percentage of the various elements in SiCl 3 Br Find the molar mass of the compound by adding up the masses of each atom in the compound. Calculate the mass due to the component in the compound you are for which you are solving by adding up the mass of these atoms. Divide the mass due to the component by the total molar mass of the compound and multiply by 100.

What is the percentage of the various elements in Ammonium sulfate? Find the molar mass of the compound by adding up the masses of each atom in the compound. Calculate the mass due to the component in the compound you are for which you are solving by adding up the mass of these atoms. Divide the mass due to the component by the total molar mass of the compound and multiply by 100.
