An impure sample of CaC₂O₄.H2O is analysed using TGA  technique. TG Cure of the sample indicates the total mass change from 85 mg to 30.7 mg when this sample was healed upto 900O C. Calculate the % purity of the sample. 

In thermogravimetric analysis (TGA), the technique measures the change in mass of a sample as it is subjected to increasing temperatures. The information provided indicates that the sample undergoes a mass change from 85 mg to 30.7 mg when heated up to 900°C. The total mass loss corresponds to the decomposition of CaC2O4·H2O, leaving behind the residue of impurities.

To calculate the percentage purity of the sample, we need to consider the stoichiometry of CaC2O4·H2O and the mass lost due to the decomposition of the ____ ______ ________ _______ ____ ______ ________ ________ ___ __________ ___.
