It is found that 2.0 x 10-5 mol 222Rn (t1/2 = 3.82 d, atom mass = 222) has seeped into a closed basement with a volume of 2.0 x 10° m³. The decay product of Radon Rn ) is 18 Po that will further decay into other nuclei. However, for simplicity, assume that8 Po is the product you can measure before it further decays. Calculate in grams how much s Po (assume the AMU is 218) will be generated after 8 hours of decay? 84 A. 3.61 x 10-5 g B. 2.55 x 104 g C. 3.61 x 104 g D. 8.42 x 103 g

Question
It is found that 2.0 x 10-5 mol 222Rn (t1/2 = 3.82 d, atom mass = 222) has seeped into a closed basement with a volume of 2.0 x 103 m3. The decay product of Radon Rn ) is 18 Po that will further decay into other nuclei. However, for simplicity, assume that 218 Po is the product you can measure before it further decays. Calculate in grams how much 218 Po (assume the AMU is 218) will be generated after 8 hours of decay? 84 84 A. 3.61 x 10-5 B. 2.55 x 104 g C. 3.61 x 10-4 g D. 8.42 x 10-3 g
