    1.552 moles

    Explanation:

    First, we'll begin by writing a balanced equation for the reaction showing how C8H18 is burn in air to produce CO2.

    This is illustrated below:

    2C8H18 + 25O2 - > 16CO2 + 18H2O

    Next, let us calculate the number of mole of C8H18 present in 22.1g of C8H18. This is illustrated below:

    Molar Mass of C8H18 = (12x8) + (18x1) = 96 + 18 = 114g/mol

    Mass of C8H18 = 22.1g

    Mole of C8H18 = ... ?

    Number of mole = Mass / Molar Mass

    Mole of C8H18 = 22.1/144

    Mole of C8H18 = 0.194 mole

    From the balanced equation above,

    2 moles of C8H18 produced 16 moles of CO2.

    Therefore, 0.194 mole of C8H18 will produce = (0.194x16) / 2 = 1.552 moles of CO2.

    Therefore, 1.552 moles of CO2 are emitted into the atmosphere when 22.1 g C8H18 is burned
