A 50.0 mL sample of a 0.200 M aqueous solution of Na3PO4 was added to 50.0 mL of a 0.100 M aqueous solution of BaCl2. The mixture was stirred and the precipitate was collected, dried carefully, and weighed. How many grams of precipitate should be obtained

1.02 grams

Explanation:

The reaction between Na₃PO₄ and BaCl₂ is:

2Na₃PO₄(aq) + 3BaCl₂(aq) → Ba₃(PO₄)₂(s) + 6NaCl(aq)            

We need to find the number of moles of Na₃PO₄ and BaCl₂:

Now, we need to find the limiting reactant:

We have that it is needed 0.0033 moles of Na₃PO₄ to react with BaCl₂ and we have 0.01 moles of Na₃PO₄, so the limiting reactant is BaCl₂.

The number of moles of Ba₃(PO₄)₂ is:

Finally, the mass of Ba₃(PO₄)₂ is:

Therefore, should be obtained 1.02 grams of the precipitate.

answer; natural resources;

nuclear fission produces elements that are heavier than helium.

the elements that are used in nuclear fission and their products are much heavier than helium.
