Answer: 0.04137 moles

Explanation:

Ba = 137.327amu

Cl = 35.5

BaCl2 = 137.327 + (35.5*2)

BaCl2 = 137.327 + 71

BaCl2 = 208.327amu

1 mole of BaCl2 contains 208.327 g

x mole is present in 8.62g of BaCl2

x = 8.62 * 1 / 208.327

x = 0.04137g

Its other molecule of the daughter would not have been radioactive as it did not need dATP for its replication. While each strand of the second molecule includes t, simultaneous reproduction dATP from both daughter molecules is needed so that each of those is radioactive.
