I'm stuck on half-life problems ):

1) You have to inventory various microbiological antigen serum samples in the hospital laboratory, and you observed that there is 50.0 gram sample of antigen T-cell serum that has denatured to 12.5 grams of viable macrobiotic activity in just 14.5 days on the shelf. What is the antigen T-cell serum in your opinion?

There is 12.5 grams out of 50 grams remaining after 14.5 days.

12.5=50e^{k(14.5)}

Solve for k.

Half life is given by:

T=\frac{-ln(2)}{k}

Find k from the first equation and sub into T to find the half life.

Is it me or the question is asking for "what is the serum in your opinion?" as in "Guess its definition?" :confused:

EDIT: Never mind, OP missed a key word in the question. -_-
