Copper-64 (Cu-64) has a half-life of approximately 12.7 hours. After one half-life (12.7 hours), half of the original sample would remain. Therefore, from a 2 mg sample, after 12 hours, approximately 1 mg of Cu-64 would remain, as it has not yet fully completed one full half-life.

The half life for Cu=64 is 12.7 hours. Thus, 12 hours represents 12/12.7 = 0.945 half lives.Fraction remaining = 0.5^0.945 = 0.519 remaining2 mg x 0.519 = 1.04 mg remaining
