Molarity, M = number of moles/volume of solution M=(n/V) for mixture of solutios n 1+ n 2+ n 3+ ldots= M 1 V 1+ M 2 V 2+ M 3 V 3+ ldots ( n 1+ n 2+ n 3+ ldots) × (( V 1+ V 2+ V 3+ ldots)/( V 1+ V 2+ V 3+ ldots))= M 1 V 1+ M 2 V 2+ M 3 V 3+ ldots total number of moles in the mixture =n T , total volume =V T final molarity = M T = M ( n T / V T ) ×( V 1+ V 2+ V 3+ ldots)= M 1 V 1+ M 2 V 2+ M 3 V 3+ ldots M T ×( V 1+ V 2+ V 3+ ldots)= M 1 V 1+ M 2 V 2+ M 3 V 3+ ldots or M ×( V 1+ V 2+ V 3+ ldots)= M 1 V 1+ M 2 V 2+ M 3 V 3+ ldots

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

$M_{1} + V_{1} \times M_{2} + V_{2} \times M_{3} + V_{3} + ... = M_{1} + M_{2} + M_{3}$

$M_{1} V_{1} + M_{2} V_{2} + M_{3} V_{3} + ... = M (V_{1} + V_{2} + V_{3})$

$\frac{M _{1}}{V _{1}} + \frac{M _{2}}{V _{2}} + \frac{M _{3}}{V _{3}} + ... = M (\frac{1}{V _{1}} + \frac{1}{V _{2}} + \frac{1}{V _{3}})$

$\frac{M _{1}}{V _{1}} \times \frac{M _{2}}{V _{2}} \times \frac{M _{3}}{V _{3}} + ... = M (\frac{1}{V _{1}} \times \frac{1}{V _{2}} \times \frac{1}{V _{3}})$

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

M1​+V1​×M2​+V2​×M3​+V3​+...=M1​+M2​+M3​

M1​V1​+M2​V2​+M3​V3​+...=M(V1​+V2​+V3​)

V1​M1​​+V2​M2​​+V3​M3​​+...=M(V1​1​+V2​1​+V3​1​)

V1​M1​​×V2​M2​​×V3​M3​​+...=M(V1​1​×V2​1​×V3​1​)

$M_{1} + V_{1} \times M_{2} + V_{2} \times M_{3} + V_{3} + ... = M_{1} + M_{2} + M_{3}$

$M_{1} V_{1} + M_{2} V_{2} + M_{3} V_{3} + ... = M (V_{1} + V_{2} + V_{3})$

$\frac{M _{1}}{V _{1}} + \frac{M _{2}}{V _{2}} + \frac{M _{3}}{V _{3}} + ... = M (\frac{1}{V _{1}} + \frac{1}{V _{2}} + \frac{1}{V _{3}})$

$\frac{M _{1}}{V _{1}} \times \frac{M _{2}}{V _{2}} \times \frac{M _{3}}{V _{3}} + ... = M (\frac{1}{V _{1}} \times \frac{1}{V _{2}} \times \frac{1}{V _{3}})$
