starting with 3.00 g of 4-aminophenol (molar mass = 109.13 g/mol) and excess acetic anhydride, what is the theoretical yield (in g) of acetaminophen (molar mass = 151.16 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.
