    The document discusses calculating the percent composition of elements in compounds. It defines percent as parts per hundred and explains how to calculate percent composition by dividing the mass of each element by the total mass of the compound and multiplying by 100. Sample problems are provided to demonstrate calculating percent composition for various compounds like C6H12O6, H2SO4, BaCl4, and quiz questions review calculating percent composition for H2O, NaOH, C6H10O4, and FeCl3.

    Percent Composition

    of Compounds
     What is Percent?

     How do we solve the percentage composition of


    any one/all element
    in the compound?
    What is Percent?
     Percent is defined as parts per hundred.

     For example, if a compound contains 25 g of


    chlorine in 100 g of compound, the substance
    contains 25% chlorine by mass.
    Sample problems:
    1. Calculate the percent composition by mass of
    C6H12O6.

    Steps to solve the problem:


    1. Calculate the molecular mass of C6H12O6.
    2. The percentage of each element in the
    compound is calculated by dividing the mass of
    each element by the total mass and then multiply it
    by 100.
    Sample problems:
    2. Calculate the percent composition by mass of Sulfur
    in H2SO4.
    Formula:
    Sample problems:
    3. Calculate the percent composition by mass of BaCl4.

    4. Calculate the percent composition by mass of Carbon


    in C6H12O6.
    Quiz:
    1. What is percent?
    2. Calculate the percent composition by mass of Hydrogen
    in H2O?
    3. Calculate the percent composition by mass of NaOH.
    4. Calculate the percent composition by mass of C6H10O4.
    5. Calculate the percent composition by mass of Iron in FeCl3.
