Answer (A) 6.3g Answer(B) 1.0g
Explanation / Answer
A) The mass of 1Bq of 224Ra is =(4.80*105 )*(224 u) = 1.79*10-19 kg Mass of 1 Ci of 224Ra is =(1.79*10-19 kg)(3.70*10^10) = 6.30g B) The mass of 1Bq of 224Ra is =(4.80*105 )*(226 u) = 1.81*10-19 kg Mass of 1 Ci of 224Ra is =(1.81*10-19 kg)(3.70*10^10) Simplifying we get the answer.
