A car tyre has a mass of 15 kg. Tyres can be disposed of using a process known as pyrolysis. 31% by mass of a car tyre can be converted into carbon and 26% by mass can be converted into gas, which is predominantly methane. If 10,0000 tyres are treated in this way each year in a city. What will be the volume of methane produced in this process at 600 "C?
