The first steps in the radioactive decay of 257Uuh involves the rapid and successive emission of 4 alpha particles. [Note: Uuh is the symbol for ununhexium, which is element number 116.] An original sample of 0.384 micrograms of 257Uuh yielded 0.240 micrograms of the appropriate product nuclide after 41.01 microseconds of decay had occurred. What is the half-life (microseconds) for 257Uuh
