(C) Given: Power $P = 100 \ W$,Voltage $V = 125 \ V$,Electrochemical equivalent $Z = 0.367 	imes 10^{-6} \ kg/C$,Time $t = 60 \ s$.Using the formula for power,$P = VI$,we find the current $I$:$I = \frac{P}{V} = \frac{100}{125} = 0.8 \ A$.According to Faraday's law of electrolysis,the mass $m$ of the substance deposited is given by $m = ZIt$.Substituting the values:$m = (0.367 	imes 10^{-6} \ kg/C) 	imes (0.8 \ A) 	imes (60 \ s)$$m = 0.367 	imes 10^{-6} 	imes 48 \ kg$$m = 17.616 	imes 10^{-6} \ kg$Since $1 \ kg = 10^6 \ mg$,we have:$m = 17.616 	imes 10^{-6} 	imes 10^6 \ mg = 17.616 \ mg \approx 17.6 \ mg$.

$A$ power of $100 \ W$ is used at $125 \ V$ to produce chlorine by electrolysis. How many $mg$ of chlorine are produced per minute? (The electrochemical equivalent of chlorine is $0.367 \times 10^{-6} \ kg/C$)
