The % of the fixed carbon can be given by _________(a) %C=[loss in wei

1.	The % of the fixed carbon can be given by _________(a) %C=[loss in weight due to removal of C/weight of coal sample]100(b) %C=[weight of coal/12100](c) %C=100-(% of ash)(d) %C=100-(% of moisture+% of volatile matter+% of ash)The question was posed to me in final exam.Enquiry is from Analysis of Coal and Selection topic in portion Fuel Technologies of Applied Chemistry
Answer» Correct OPTION is (d) %C=100-(% of moisture+% of VOLATILE matter+% of ash) EASY explanation: The % of carbon can be determined easily because the coal will have the highest AMOUNT of carbon CONTENT. So, from 100 we have to subtract the other contents % to get % of carbon.
