The element Meitnerium, named in honour of Lise Meitner, an Austrian physicist and mathematician, and first synthesized in 1982, has a listed atomic weight (mass) of 268. There are only two main known isotopes of meitnerium: Mt - 276 and Mt - 266.Determine the relative abundance in of each isotope in the synthesized material. To make it easy, use whole numbers (intergers) for the atomic mass of the meitnerium isotopes in your calculations.
1. Mt - 266: 88% Mt - 276: 22%
2. Mt - 265: 85% Mt - 276: 15%
3. Mt - 266: 88% Mt - 276: 22%
4. Mt - 266: 85% Mt - 276: 15%
5. Mt - 266: 80% Mt - 276: 20%
Use bond dissociation energies to determine how much energy can be generated per mole of iso-octane.
An automobile engine requires a carburetor or fuel inector to mix the fuel with air. The fuel and air must be mixed in a particlar ratio to achieve maximum efficiency in the combustion of the fuel.
