The negative $\text{Zn}$ pole of a Daniell cell, sending a constant current through a circuit, decreases in mass by $0.13\text{g}$ in $30\text{minutes}$. If the electrochemical equivalent of $\text{Zn}$ and $\text{Cu}$ are $32.5$ and $31.5$ (arbitrary units or mass ratio) respectively, the increase in the mass of the positive $\text{Cu}$ pole in this time is:
