Final answer:
To find the volume of carbon dioxide gas produced, we need to use stoichiometry and the ideal gas law. The balanced chemical equation shows that 2 moles of phosphoric acid react with 3 moles of ferric carbonate to produce 6 moles of carbon dioxide gas.
Step-by-step explanation:
The question asks how many milliters of carbon dioxide gas can be produced at 78°C at 45.5 psi pressure with 900.0 mL of 3.00M phosphoric acid and 435 grams of ferric carbonate. To find the volume of carbon dioxide gas, we need to use stoichiometry and the ideal gas law. The balanced chemical equation for the reaction between phosphoric acid and ferric carbonate is given as:
2H3PO4 + 3Fe2(CO3)3 → 6CO2 + 6H2O + 2Fe3(PO4)2
From the equation, we can see that 2 moles of phosphoric acid react with 3 moles of ferric carbonate to produce 6 moles of carbon dioxide gas.
