<u>Answer:</u>
<em>To answer the question we need to know the half-life of fluorine for reference we have chlorine half-life as 110. The fraction of chlorine remaining would be given by
</em>
<u>Explanation:</u>
Here we know and is known as the number of Half-life that have elapsed during this process Now we are giving the time of start as 8 a.m. and time of finishing at 1:30 p.m., so the time between is 5 ½ hours. Which on converting in minutes will give 330 minutes.
So Half Life elapsed would be given by =
Hence the amount remaining would be =
Answer : The correct option is, (C) 0.675 M
Explanation :
Using neutralization law,
where,
= concentration of
= 13.5 M
= concentration of diluted solution = ?
= volume of
= 25.0 ml = 0.0250 L
conversion used : (1 L = 1000 mL)
= volume of diluted solution = 0.500 L
Now put all the given values in the above law, we get the concentration of the diluted solution.
Therefore, the concentration of the diluted solution is 0.675 M
