Answer:
=14.8 grams
Explanation:
The remaining amount is normally calculated using the formula:
Remaining mass= 1/2ⁿ × Original mass where n is the number of half-lives.
Therefore, original mass= Remaining mass × 2ⁿ
Remaining mass= 2.2 grams
Number of half lives= 2.75 half lives
Original mass= 2.2g × 2²·⁷⁵
=14.8 grams
