actly 2.5 g was weighed into silica crucible. After heating for an hour at 110 0C, the residue was weighed 2.415 gm. The crucible was then covered and strongly heated for 7 to 10 minutes at 950 C. The residue weighed 1.528 g. The crucible was then heated without cover until a constant weight was obtained. The last residue was found to weigh 0.245 g. Calculate the % of moisture, volatile matter, ash and fixed carbon in the coal sample

Question
Exactly 2.5 g was weighed into silica crucible. After heating for an hour at 110 0C,
the residue was weighed 2.415 gm. The crucible was then covered and strongly heated
for 7 to 10 minutes at 950 C. The residue weighed 1.528 g. The crucible was then
heated without cover until a constant weight was obtained. The last residue was found
to weigh 0.245 g.
Calculate the % of moisture, volatile matter, ash and fixed carbon in the coal sample
