Stoichiometry problem: mercury and bromine producing HgBr2

[suspenc3]

Mercury and bromine will react with each other to produce mercury(II) bromide.
a.)What mass is produced from the reaction of 10.0g Hg and 10.0g Br2?What mass of which reagent is left unreacted?

b.)what mass of HgBr2 is produced from the reaction of 5.00mL of mercury?(d=13.5g/mL) and 5.00mL of bromine(d=3.12g/mL)?

If someone could give me a clue where to start? My High school had a terrible chemistry program, I've never seen any of this before.

Please, any help would be appreciated.

You can start by writing the reaction which takes place. That will tell you, how many moles of the product is formed per mole of the reactant consumed.
(Are you familiar with these terms?)
