WebAfter 24 months: 125 A remaining (half of the remaining 250 A have decayed to B) Therefore, after two years, 125 parent isotopes (A) would remain in the sample. To calculate the number of daughter isotopes (B) in the sample, we can subtract the number of parent isotopes (A) from the original number of parent isotopes (A): B = 2000 - 125 = 1875.
