The Ideal Gas Law
4PRACTICE PROBLEM
The reaction of oxalic acid (H2C2O4) and potassium chlorate (KClO4) produces potassium carbonate (K2CO3), water, gas X, and gas Y:
H2C2O4(aq) + KClO4(aq) → K2CO3(aq) + H2O(l) + X(g) + Y(g)
The gases were collected and placed in a 1.50 L vessel at 27.0°C. The final pressure of the vessel is 552 mmHg. Calculate the total moles of gas present.
