b) The TGA Curve below shows the decomposition of calcium salicylate monohydrate (mw 332 g/mol). Starting with an initial sample mass of 16.55 mg, calculate the mass of the sample remaininq when it is heated to (i) 350 oc and (ii) 800 oc. The first step is loss Of H20 (mw 18 g/mol), followed by loss Of C703H6 (mw 138 g/mol), then C6H4 (mw 76 g/mol) and finally C02 (mw 44 g/mol). Give your answers to two decimal places and show your work. olqxe CACH06 H,O CaC. H,0 20- 40 CaC,0,H, 60 Mass loss (%)
