40 g was weighed in a silica crucible. After heating for one hour at 110°C, the residue weighed 1.10 g. The crucible next was covered with a vented lid and strongly heated for exactly7 minutes at 950–20°C. The residue weighed 1 g. The crucible was then heated without cover, until a constant weight was obtained. The last residue was found to weigh 0.21g.Calculate the %'results of the above analysis.O A Moisture = 10.24%Volatile matter = 20.40%Ash = 7%B. Moisture = 26.14%Volatile matter = 15.15%Ash = 21%OC Moisture = 19.02%Volatile matter = 10.10%Ash = 13%OD Moisture = 21.42%Volatile matter = 7.14%Ash = 15% |
