Answer:
because it has lighter molecules.
The gram-formula mass of citric acid is 3(1)+6(12)+5(1)+16(7)=192 g/mol.
This means that in 13.00 grams of citric acid, there are 13.00/192 = 0.067 moles.
From the equation, we know that for every 1 mole of citric acid that is consumed, 3 moles of carbon dioxide are produced.
This means that there are 3(0.067)=0.203 moles.
Since the gram-formula mass of carbon dioxide is 12+2(16)=44 g/mol, meaning it has a mass of 0.203(44)=8.93 g
Answer:
0.050 mol
Explanation:
The reaction that takes place is:
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.
