Methane can be obtained from coal using a process called the gasification of coal. The global chemical equation for the reaction is as follows:
C + 2H2 à CH4
a) If coal is made up of 44% pure carbon, by mass, calculate the maximum volume of methane which could be produced from 2.0 kg of coal at NTP conditions.
b) Calculate the theoretical yield percentage if 525 L of methane are actually produced at NTP conditions.
