In proximate analysis of coal, %fixed carbon = __________

In proximate analysis of coal, %fixed carbon = __________ Correct Answer 100 – % (ash + volatile matter + moisture)

In proximate analysis of coal, firstly percentage of ash, volatile matter and moisture is found out. Percentage of fixed carbon can be found out by subtracting the above percentages from 100 since coal consists of ash, moisture, volatile matter and fixed carbon.
