Answer 1

The amount of the radioactive substance is 374.6 g

How to determine the amount of radioactive substance?

The given parameters are:

• Initial, a = 424 mg
• Rate, r = 6%
• Time, t = 2 hours

The amount of the radioactive substance is calculated as:

A(t) = a(1 - r)^t

This gives

A(t) = 424 * (1 - 6%)^t

At 2 hours, we have:

A(2) = 424 * (1 - 6%)^2

Evaluate

A(2) = 374.6

Hence, the amount of the radioactive substance is 374.6 g
