Well, you need to know what the chemical reaction of carbon and iron(III) oxide is first. There's a hint in the problem that a gas will be formed; figure out what gas it is and how many moles of it you get.
Then, use the ideal gas equation to find the volume. Pressure is one atmosphere probably, temperature is probably room temperature.
