If 0.035pC of charge is transferred via the movement of Al3+ ions, how many of these ions must have been transferred in total?

Could someone explain how to do this? I have no idea where to start

Start by converting the charge of one Al^3+ ion to coulombs? How might you do that?

Next, can you convert the 0.035 pC to coulombs? How might this be useful?
