4.79 x 10⁻⁷moldm⁻³

Explanation:

Given parameters:

    pOH of RbOH = 6.32

Unknown:

Molarity of the base = ?

Solution:        

    The pH or pOH scale is used for expressing the level of acidity alkalinity of aqueous solutions.

                      pOH = -log[OH⁻]

  we know the pOH to be 6.32

               6.32 = -log[OH⁻]

               [OH⁻]  = inverse log₁₀(6.32)

                [OH⁻] =  4.79 x 10⁻⁷moldm⁻³
