This is College Physics Answers with Shaun Dychko. The capacitance needed to store three microCoulombs of charge when 120 volts is applied can be found by taking the charge divided by the voltage. So, that's three times ten to the minus six Coulombs divided by 120 volts is 25.0 nanofarads.

would is be 2.5x10^-8 F if you were to leave it in scientific notation
