Calculate the Pressure

Step by Step explanation

Ferrous oxalate, FeC2O4, will decompose on heating:

FeC2O4 (s) ® FeO (s) + CO2 (g) + CO (g)
A 1.25-gram sample of FeC2O4 is added to an evacuated 2.00-liter steel vessel.
The vessel is heated to 400°C, at which point all the FeC2O4 is decomposed.
Calculate the pressure inside the vessel at 400°

Solution Preview

1 mole of ferrous oxalate gives 2 moles of gas in total (1 mole CO2 and 1 mole CO).

Find moles of FeC2O4 by dividing the 1.25 grams ...
