Final answer:

The half-life of a substance is the time required for half of the substance to decay. In this case, the substance decays at a rate of 3.23% per week. To find the half-life, we can use the formula: half-life = (ln(2)) / (decay rate) Substituting in the given decay rate of 3.23% per week gives: The half-life of the substance is 21.45 weeks.

Step-by-step explanation:

The half-life of a substance is the time required for half of the substance to decay. In this case, the substance decays at a rate of 3.23% per week. To find the half-life, we can use the formula: half-life = (ln(2)) / (decay rate) Substituting in the given decay rate of 3.23% per week gives: half-life = (ln(2)) / (0.0323) = 21.45 weeks.

the time required for half of the substance to decay. In this case, the substance decays at a rate of 3.23% per week. To find the half-life, we can use the formula: half-life = (ln(2)) / (decay rate) Substituting in the given decay rate of 3.23% per week gives: The half-life of the substance is 21.45 weeks.
