The production cost of hydrogen from a mineral acid using zinc is Rs.

1.	The production cost of hydrogen from a mineral acid using zinc is Rs. 12 per mole. How many electrons is worth of one rupee?
Answer» Solution :Reaction of mineral acid with zinc is given as `Zn+2HClrarrZnCl_(2)+H_(2)` The net reaction is `2H^(+)+2e^(-)rarrH_(2)` 1 mole of `H_(2) = 2` moles of electrons 12 rupees `= (2 xx 6.022) xx 10^(23)` electrons 1 rupee `= ?` NUMBER of electrons worth of ONE rupee `= (1)/(12)xx 2 xx 6.022 xx 10^(23)=1.004xx10^(23)`
