Answer:
Ending Amount = Beginning Amount / 2 ^ n
where 'n' = number of half-lives n = 65 / 29 = 2.2413793103
Ending Amount = 25 g / 2^2.2413793103
Ending Amount = 25 / 4.7284892286
Ending Amount = 5.2871009727 g = 5.29 g (rounded)
Step-by-step explanation:
The answer is A. this is because your are multiplying by 9 throughout
Answer:1/32
Step-by-step explanation:
Answer:
Yes
Step-by-step explanation:
