Question

How many total moles of ions are released when 0.0341 moles of Na2HPO4 dissolves completely in water

Answer 1

Answer:

0.1023 moles

Explanation:

We have this reaction

Na2HPO4 → 2Na+ + NPO4-

1 mole gives us 3 ions

Na+ has 2 ions to it

NPO4 has 1 ion

2 + 1 = 3

We multiply 3 with the number of moles to get the answer to this question

3 x 0.0341

= 0.1023 moles

So we conclude that total moles released when dissolved in water is equal to 0.1023
