Alright, so after a half-life, half of the previous number would be left. So basically,
180 g ← 0 half lives
90 g ← 1 half life
45 g ← 2 half lives
22.5 g ← 3 half lives
11.25 g ← 4 half lives
Therefore, the answer is 11.25 grams
Answer:
6^ (1/12)
Step-by-step explanation:
6 ^ 1/3
-------------
6 ^ 1/4
x^a / x^b = x^ (a-b)
6^(1/3-1/4)
Getting a common denominator)
6^(4/12-3/12)
6^1/12
