Answer:
0.050 mol
Explanation:
The reaction that takes place is:
- H₃PO₄ + 3NH₃ → (NH₄)₃PO₄
Then we convert 0.050 moles of phosphoric acid into moles of ammonium phosphate, using the stoichiometric coefficients of the reaction:
- 0.050 mol H₃PO₄ *
= 0.050 mol (NH₄)₃PO₄
Thus, the complete reaction of 0.050 moles of phosphoric acid would produce 0.050 moles of ammonium phosphate.
<u>Answer:</u> The number of moles of is 0.05 moles.
<u>Explanation:</u>
To calculate the molarity of solution, we use the equation:
We are given:
Molarity of solution = 0.10 mol/L
Volume of solution = 1 L
Putting values in above equation, we get:
The chemical reaction for the ionization of sodium sulfate follows the equation:
By Stoichiometry of the reaction:
2 moles of sodium ions are produced by 1 mole of sodium sulfate
So, 0.10 moles of sodium ions will be produced by = of sodium sulfate.
Hence, the number of moles of is 0.05 moles.
