A sample of iron ore weighing 0.2370g was dissolved in an excess of a dilute acid solution. All the iron was first converted to Fe(II) ions. The solution then required 23.30mL of 0.0212 MKMnO4 for oxidation to Fe(III) ions. Compute the percent by mass of iron in the ore.

A fossil was analyzed and determined to have a carbon-14 : All living things contain carbon. Most of this carbon is stable carbon-12. Nevertheless, a small percentage will be carbon-14, a radioactive isotope of carbon that decays with time. As living things eat and breathe, carbon is constantly recycled a..
