Answer:
0.15 L
Explanation:
Step 1. Calculate the <em>moles of KF.</em>
Molar mass = 58.10 g/mol
Moles of KF = 8.0 × 1/58.10
Moles of KF = 0.138 mol KF
===============
Step 2. Calculate the <em>volume of KF
</em>
c = n/V Multiply both sides by V
V = 0.138 × 1/0.89
V = 0.15 L
Noble gases.

fixed naming!
1 in 10, or 1/10, or 0.1 dilution factor It may be wrong but this is what I have!
Chemical properties are mainly determined by the number of valence electrons (electrons which can be gained, lost, or shared) in the atom.
In my opinion, the answer is the second option.
