The concentration of a saturated bacl2 solution is 1.75 m (mol/liter) and the concentration of a saturated na2so4 solution is 2.0 m. calculate the theoretical yield, in grams, and the percent yield for your synthesis of the barium white pigment.

a) The theoretical yield is 408.45g of

b) Percent yield =

Explanation:

1. First determine the numer of moles of and .

Molarity is expressed as:

M=

- For the

M=

Therefore there are 1.75 moles of

- For the

M=}{1Lsolution}" alt="Na_{2}SO_{4}" />}{1Lsolution}" />

Therefore there are 2.0 moles of

2. Write the balanced chemical equation for the synthesis of the barium white pigment, :

3. Determine the limiting reagent.

To determine the limiting reagent divide the number of moles by the stoichiometric coefficient of each compound:

- For the :

- For the :

As the is the smalles quantity, this is the limiting reagent.

4. Calculate the mass in grams of the barium white pigment produced from the limiting reagent.

5. The percent yield for your synthesis of the barium white pigment will be calculated using the following equation:

Percent yield =

Percent yield =

The real yield is the quantity of barium white pigment you obtained in the laboratory.

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
