A $6.0$ - $\mathrm { V }$ Battery That Can Store $500.0 \mathrm {~J}$

A $6.0$ - $\mathrm { V }$ battery that can store $500.0 \mathrm {~J}$ of energy is connected to a resistor. How much charge must flow between the battery's terminals to completely drain the battery if it is fully charged? Assume that the voltage of the battery remains the same until it is totally drained.

A) $0.010 \mathrm { C }$
B) $3000 \mathrm { C }$
C) $83 \mathrm { C }$
D) $0.07 \mathrm { C }$
