<span>There
are a number of ways to express concentration of a solution. This includes
molarity. Molarity is expressed as the number of moles of solute per volume of
the solution. We calculate as follows:
Molarity = 78.6 g KF ( 1 mol / 58.1 g ) / .225 L = 6.013 mol / L KF solution</span>
The cosine of angle X is
By the Pythagorean theorem, we have
Then
Multiplying numerator and denominator by 2, we get
