An aluminium ore sample was dissolved in HNO3, filtered and precipitated into Al(OH)3 after the reaction with a base. The precipitate was subsequently washed and ignited into alumina, Al2O3 which was later cooled in a dessicator and weighed 0.1095 g. i) Determine the gravimetric factor for the above analysis.
