Am I doing these right?

    Am I doing these right?!?!

    1)How many moles of Li3N will be produced if you begin with 8.5 moles of Li ?

    **Do I just find the moles for 3N and add them to the 8.5 moles of Li?**

    2)Calculate the number of atoms in 20.5 g Carbon

    **I guess I would Multiply Carbon's atoms by 20.5?**

    3)What are the three basic types of compounds that are used as antacids?

    **I have no idea whatsoever! I've looked everywhere for the answer. Please help!**

    1) write first the equation
    2) 12 gr C contains 6.027*10^23 atoms how mutch is this for 20.5 g?
    3) antacids is this formic acid?

    Like mit already said first write the equation, balance it, then determine the limiting reactant.
