Final answer:

The half-life of the substance is 6.13 days.

Step-by-step explanation:

The half-life of a substance can be calculated using the formula:

t1/2 = 0.693 / k

where t1/2 is the half-life and k is the rate constant. In this case, the sample has a mass of 38 grams and a k-value of 0.113. Therefore, the half-life can be calculated as:

t1/2 = 0.693 / 0.113 = 6.13 days (rounded to the nearest tenth).
