Question

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

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

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

• C. $\frac{M_{1}}{V_{1}} + \frac{M_{2}}{V_{2}} + \frac{M_{3}}{V_{3}} + ....M\left( \frac{1}{V_{1}} + \frac{1}{V_{2}} + \frac{1}{V_{3}} \right)$
• D. $\frac{M_{1}}{V_{1}} \times \frac{M_{2}}{V_{2}} \times \frac{M_{3}}{V_{3}} + ... = M_{1}\left( \frac{1}{V_{1}} \times \frac{1}{V_{2}} \times \frac{1}{V_{3}} \right)$

Answer 1

Answer: (B)

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