What is the concentration in molarity of a solution which is 10.81 %m/v octane (MM = 114.2 g/mol) in hexane (MM = 86.18 g/mol)?

Americium-241 undergoes fission to produce three neutrons per fission event. if a neutron-absorbing material is mixed in with this sample so that the rate of neutron production drops down to 1.8 neutrons per fission event, which will be effective at achieving a critical mass? check all that apply. remove a deflective shield surrounding the sample. remove absorbent material mixed in with the sample. compress the sample of americium-241.
