1.	A certain current liberates `0.5g` of hydrogen in 2 hours. How many grams of copper can be liberated by the same current flowing for the same time in a copper sulphate solution ?A. ` 12.7 g`B. ` 15.9 g`C. ` 31.8 g`D. ` 45 g`
Answer» Correct Answer - C `("Weight of" Cu)/("Weight of" H_2) = (Eq."weifht" of Cu)/(Eq."weight" . Of H)` `("Weight of" Cu)/(0.50) = ( 63.6//2)/1` Weight of ` Cu = 15.9 g`.
