A sample of coal weighing $2\mathrm{.}345$ g was placed in a crucible of $10\mathrm{.}567$ g in an oven and maintained at $100\backslash$deg C for $1$ hour. The sample was then removed, cooled in a desiccator, and reweighed. This procedure was repeated until a constant total mass of $11\mathrm{.}789$ g was attained. A second coal sample of mass $1\mathrm{.}235$ g in a crucible of mass $9\mathrm{.}876$ g was heated with a lid in a furnace at $920\backslash$deg C for $7$ minutes. On cooling and reweighing, the total mass was $11\mathrm{.}456$ g$.$ This sample was then heated without a lid in the same furnace maintained at $815\backslash$deg C until a constant total mass of $10\mathrm{.}987$ g was attained. Determine the proximate analysis of the sample on ash free basis and dry ash basis.
