Molarity is number of moles of solute per one liter of solution. The symbol for molarity is a capital M. The molarity of the given solution will be 3.125M
A solution is a mixture of two or more substances in which neither of substance changes chemically. For example, the salt water is a solution that contains the water (the solvent) and salt (the solute). Concentration is amount of dissolved substance in a solution. In other words, it is amount of stuff that has been mixed into the liquid. Concentration is usually measured in the molarity.
Given that,
Number of moles= 1
Volume = 320ml= 0.320 L
Molarity= No of moles of solute/ Volume of solution in L
= 1/ 0.320
= 3.125 M

Answer:
2 KF ₍s₎ → F₂ ₍g₎ + 2 K ₍s₎
Explanation:
Chemical Formula of Potassium Fluoride = KF
Chemical Formula of Fluorine Gas = F₂
Chemical Formula of Solid Potassium = K
Step 1: Write the unbalance chemical equation,
KF → F₂ + K
Step 2: Balance Fluorine Atoms;
As there is one fluorine atom on left hand side and two fluorine atoms on right hand site therefore, to balance them multiply KF on left hand side by 2 i.e.
2 KF → F₂ + K
Step 3: Balance Potassium Atoms;
As there are two potassium atoms on left hand side and one potassium atom on right hand site therefore, to balance them multiply K on right hand side by 2 i.e.
2 KF → F₂ + 2 K
Step 4: Assign Physical states as,
2 KF ₍s₎ → F₂ ₍g₎ + 2 K ₍s₎
