Heating substances in airWatch

The question didn't give me any info about the temp. it just said ' what volume of gas would be produced when 1.06g of the pigment is heated in air' i just thought i had to use the ideal gas equation since i was working out a volume??
OCR A use both PV = nRT and 1 mol = 24.0 dm3, the second method will do if they don't state T.
