Answer:

Explanation:

DNA sequencing has brought us the genetic species concept. In this model, species are defined by genetic isolation rather than reproductive isolation. Species may be more or less identical morphologically but differences in DNA determine if a population is a separate species or not. It also allows them to it allows them to study and analyze the species.

How long will it take for 475 mg of a sample of radium-225, which has a half-life of about 15 days, to decay to 30 mg
zlopas [31]
<h3>Answer:</h3>

60 days

<h3>Explanation:</h3>

Half-life is the amount of time it takes half of a substance to decay away.

Guess and Check

One method for solving half-life problems like this is to guess and check. To do this, we can continue to divide 475mg by 2 until we get to 30mg.

  • 475 ÷ 2 = 237.5
  • 237.5 ÷ 2 = 118.75
  • 118.75 ÷ 2 = 59.375
  • 59.375 ÷ 2 = 29.6875

As seen here, it takes approximately 4 half-lives for this sample of Ra-225 to decay to 30mg. Now, we can multiply 4 by the length of the half-life, 15 days.

  • 4 * 15 = 60 days.

Fractions

Another way to solve this is to use fractions.

  • 30 is about 1/16 of 475
  • 16 is equivalent to 2^{4}.

This means that it takes 4 half-lives for 475mg to decay to 30mg. Using the same method above, we can tell that 4 half-lives are 60 days.

Important Note

In this question, I rounded occasionally. So, not all of the values are exact, but they are all very close.
