Quizplus · Accepted Answer

The decay of a substance can be calculated using the formula: N(t) = N0 * (1/2)^(t/T), where N(t) is the remaining quantity, N0 is the initial quantity, t is the time, and T is the half-life. Solving for t when N(t) = 1 gram, N0 = 64 grams, and T = 25.3 days, we find t ≈ 151.8 days.

The Half-Life of Phosphorous-33 Is 25
