Normally people who try to help will give you enough to help you get started, so you will be able to tackle this on your own. You learn very little if someone else does ALL the work for you.

So let's get started. First try to find the number of moles of each reactant available.

anonymous · Answer

how would you do that

anonymous · Answer

For each reactant the number of moles ids the mass divided by the molar mass.

How many moles of each reactant do you have?

What do you not understand about the question?

anonymous · Answer

everything

aaronq · Answer

I'll help you out with the first step, to find moles use:

                $\large \sf moles=\dfrac{mass}{Molar~mass}$
