What compound are you trying to make?
I would write an equation, something like this:
RMgX + HOH ==> RH + MgXOH
I'm assuming you aren't trying t make the RH compound but this is one method for preparing alkanes or ArH
Then use freshman stoichiometry to calculate the mass of water from the reaction that will react with the amount of the phenylMg Br.
