WebHint: The original 1 mg sample is a mix of 12 C and 14 C with atomic masses of 12 and 14 dalton (atomic mass units) respectively. Use that to find how many 14 C atoms were there initially, and then find the number remaining at this time from known decay rate. The number remaining will be more than 10 18, so divide your answer by 10 18 and give ...
