the answer is E. 2.0 M nacl
Answer:
ice
Explanation:
uhh concrete has rougher surface
For this problem, we use the formula for
radioactive decay which is expressed as follows:<span>
An = Aoe^-kt
where An is the amount left after time t, Ao is
the initial amount and k is a constant. </span>
<span>
</span>
<span>We can use the equation above to find the percent of the original substance at a given time. However, the time given here is equal to the half life of C-14. So the percent left would be 50% or half the original.

There are 8 oxygens if you multiply the 4 by the 2
