A sample of ore containing Technetium weighed (4.470x10^3) g. This sample was heated in a solution of nitric acid which dissolved the technetium ion producing (7.20x10^1) g of technetium (III) nitrate (Tc(NO3)3). The acidity of the solution as adjusted and Hydrogen sulfide gas was bubbled into the solution producing (5.3900x10^1) g of technetium (III) sulfide (Tc2S3). What is the percentage of Technetium in the original sample? Molar Mass Tc = 98.00 g/mol Molar Mass To(NO3)3 = 284.03 g/ mol Molar Mass Tc2S3 = 292.20 g /mol Please answer the queshon to the appropriate number of significant figures and in scientific notation. Note: Your answer is assumed to be reduced to the highest power possible.
