Calculate the molarity of a solution that contains 0.250 moles of kf in 0.500 l of water

Molarity can be defined as the number of moles of solute in 1 L of solution.

M = n/V

Where M is the molarity of the solution (M or mol/L), n is the moles of the solute (mol) and V is the volume of the solution (L).

Here, solute is KF.

n = 0.250 mol
V = 0.500 L
M = ?

By applying the formula,
   M = 0.250 mol / 0.500 L
   M = 0.500 mol/L

Hence, the molarity of KF solution is 0.500 mol/L.

Okay well gravitational energy is matter forced by gravity making energy though the kinetic energy then the electric energy produces electricity from the kinetic energy and the kinetic energy gets its energy from the gravitational energy. was that the answer you wanted or something else?
