Fermium-253 has a half life of three days. a sample contains 400 g. how long will it take for the sample to decay to 100 g? number of half lives: 1, 2, 3, or 6? number of days: 3, 4, 5, or 6?

Number of half-lives= 2    Number of days= 6

How many grams of fermium will remain after fifteen days= 12.5

What formula would you use to calculate the mass of fermium-253 remaining after d days= option B (f(d)=400(0.794)d)

How many grams of fermium will remain after twenty-three days= 1.986 g
