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.

2.) Suppose you're attempting to measure the density of a liquid that is highly volatile (it evaporates quickly). If you first measure the volume and then several minutes later you measure the mass of the liquid will the measured density be higher than the true value, lower than the true value, or the true density of the liquid. [It helps to understand this problem with the density equation.]
How do you expresse the volume in cubic angstroms when the atomic radius is 1.76?
