Problem

A saturated solution of MX is prepared

K_{\text{sp}}

of MX is

a \times 10^{-b}

. If

10^{-7}

mol of

\text{MNO}_3

are added in 1 L of this solution conductivity of this solution is

55 \times 10^{-7}\,\text{S m}^{-1}

\lambda_{\text{M}^+}^\circ = 6 \times 10^{-3}\,\text{S m}^2\,\text{mol}^{-1}

\lambda_{\text{X}^-}^\circ = 8 \times 10^{-3}

\lambda_{\text{NO}_3^-}^\circ = 7 \times 10^{-3}

Find the value of (a + b)? Given that

10 < a < 100
