Answer:
= 28.745 g
Explanation:
Half life is the time taken by a radioactive element to decay by half the original amount.
Therefore;
New mass = Original mass × (1/2)^n
Where n is the number of half lives, in this case, n = 20/5.27 = 3.795
Therefore;
New mass = 399 g × (1/2)^3.795
<u> = 28.745 g</u>
B. since Phosphorus has an atomic mass of 30.974 (larger) than Magnesium which is 24.305 (smaller)
