Answer:
Approximately (rounded to two significant figures.)
Explanation:
The unit of concentration is the same as
(moles per liter.) On the other hand, the volume of both the
solution and the original
solution here are in milliliters. Convert these two volumes to liters:
.
.
Calculate the number of moles of in that
of
solution:
.
reacts with
at a one-to-one ratio:
.
Coefficient ratio:
.
In other words, one mole of would neutralize exactly one mole of
. In this titration,
of
was required. Therefore, the same amount of
should be present in the original solution:
.
Calculate the concentration of the original solution:

Answer:
The answer to your question is given below.
Explanation:
Potassium (K) has 19 electrons with electronic configuration of 2, 8, 8, 1.
Fluorine (F) has 9 electrons with electronic configuration of 2, 7.
Fluorine needs 1 electron to complete it's octet configuration.
Hence, potassium (K), will lose 1 electron to fluorine (F) to form potassium ion (K+) with electronic configuration of 2, 8, 8. The fluorine atom (F) will receive the 1 electron from potassium to form the fluoride ion (F-) with electronic configuration of 2, 8.
