Question

If $m_{A}$ gram of a metal $A$ displaces $m_{B}$ gram of another metal B from its salt solution and if the equivalent mass are $E_{A}$ and $E_{B}$ respectively then equivalent mass of $A$ can be expressed as:

• A. $E_{A}=\frac{m_{A}}{m_{B}} \times E_{B}$
• B. $E_{A}=\frac{m_{A}\times m_{B}}{E_{B}}$
• C. $E_{A}=\frac{m_{B}}{m_{A}}\times E_{B}$
• D. $E_{A}=\sqrt{\frac{m_{A} }{m_{B}}\times E_{B}}$

Answer 1

Answer: (A)

Correct answer is (a) $E_{A}=\frac{m_{A}}{m_{B}} \times E_{B}$
