Molarity equation of a mixture of solutions of same substance is given by

Chemistry · Class 11 · CBSE — Some Basic Concepts of Chemistry

M₁ + V₁ × M₂₊V₂ × M₃ + V₃ + … = M₁ + M₂ + M₃
M₁V₁ + M₂V₂ + M₃V₃ + … = M(V₁ + V₂ + V₃)
\(\frac{M_{1}}{V_{1}}+\frac{M_{2}}{V_{2}}+\frac{M_{3}}{V_{3}}+\ldots=M\left(\frac{1}{V_{1}}+\frac{1}{V_{2}}+\frac{1}{V_{3}}\right)\)
\(\frac{M_{1}}{V_{1}} \times \frac{M_{2}}{V_{2}} \times \frac{M_{3}}{V_{3}}+\ldots=M_{1}\left(\frac{1}{V_{1}} \times \frac{1}{V_{2}} \times \frac{1}{V_{3}}\right)\)

Answer

(B) M 1 V 1 + M 2 V 2 + M 3 V 3 + … = M ( V 1 + V 2 + V 3 )
