MAXImum [283]

Answer:

<h3>The answer is 0.42 g/mL</h3>

Explanation:

The density of a substance can be found by using the formula

$density = \frac{mass}{volume} \\$

From the question

mass = 8.11 g

volume = final volume of water - initial volume of water

volume = 44.72 - 25.26 = 19.46 mL

We have

If the half-life of a radionulide is 1 month, what percent remains after 4 months?

Aliun [14]

Answer:

6.25% of the original amount

Explanation:

half-life means that half is gone for every certain period of time. Because the half life is 1 month, only half of the 'radionulide' is left every month.

after 1 month= 50%

after 2 months= 25%

after 3 months= 12.5%

after 4 months= 6.25%
