HELLLPP....Bromobenzene reaction with Magnesium to create its grignard reagent?

I cant figure out how to balance the equation....im trying to see which one is excess and which one is limited...(I cant connect the things ive learned in gen chem to this problem)....is it already in a 1 to 1 molar ratio...PLZZZ HELP FASTTT THANKSss

Update:

oh ok nvm i got it.. sorry i didnt give the mass of each product, but i guess all i needed to know was that 1 mole of each reactant produces one mole of product (their all 1 to 1)...and yah in my experiment the Bromobenzene is in excess...thanks for answering so fast!

    Mg(s) turnings are in excess. In organic, the reagents are usually in excess to the organic starting material, which is generally for economical reasons (magnesium metal is a lot cheaper than bromobenzene). Reaction is simply : Mg (s) + C6H5Br ---> C6H5MgBr carried out in some solvent like Et2O or THF.

    2 Ph-Br + 2 Mg = 2 Ph-Mg-Br + Br^_

    Hey this is the basic equation . & Ph stands for phenyl Whose molecular formula is C6H5-

    I hope this helps you :-)
