A) in the ratio of the atomic weights of copper and silver
B) in the ratio of the density of copper and silver
C) in the ratio of half the atomic weight of copper to the atomic weight of silver
D) in the ratio of half the atomic weight of copper to half the atomic weight of silver
Correct Answer: C
Solution :
Being in series, \[Q\] is equal to same \[\therefore \]\[m\propto W\propto \]atomic weight / valency So,\[\frac{{{m}_{cu}}}{{{m}_{Ag}}}=\frac{atomic\,\,weight\,\,of\,\,Cu}{atomic\,\,weight\,\,of\,\,Ag}\times \frac{valency\,\,of\,\,Ag}{valency\,\,of\,\,Cu}\] \[=\frac{1}{2}\times \frac{atomic\,\,weight\,\,of\,Cu}{atomic\,\,weight\,\,of\,\,Ag}\]
