Answer to Problem 120A
The grams of oxygen is
Explanation of Solution
The given mass of sulfur is
Stoichiometry is a branch of chemistry that deals with calculating the quantities involved in
The number of atoms, molecules, or moles; mass; and volume are some examples of different parameters that can be used to interpret a balanced chemical equation.
The given equation to produce sulfur trioxide in balanced form is given as
The stoichiometry of sulfur and oxygen is in
The number of moles is given as
The molecular mass of sulfur is
To calculate the number of moles of sulfur, substitute the values in the above formula:
The stoichiometry between sulfur and oxygen can be written as
To calculate the number of moles of oxygen, substitute the values in above formula:
To calculate the mass of oxygen, substitute the values in number of moles formula:
