Question

Fe3O4 (s) + 4CO (g) -> 3Fe (s) + 4CO2 (g)

694.6 g of Fe3O4 are mixed with CO (V= 301 L, P=1.2 atm, T = 28C) and allowed to react. After the reaction is complete, the gasesare separated and measured. What is the volume of CO2 formed if thepressure is still 1.2 atm but the temperature has risen to 35C?

Molecular weight of Fe3O4 is 694.6 g/mole. R = 0.08206 Latm/mole K

I think this is a PV = nRT problem but I'm not sure how to dealwith the change in temperature. I have all of the values for theequation, except for n, but I can calculate that. So I'm not reallysure how I can use the equation to solve the problem.
