Consider the following unbalanced reaction:
C(s) + S8(s) → CS2(l)
How many grams of carbon disulfide will be produced if 8.80 g of C and 17.2 g of S8 are allowed to react completely?

do you know what units you use in stoichiometric problems?

nope you ALWAYS use moles
so to solve this problem:
(1) balance the reaction
(2) convert grams of reactants to moles of reactants ...moles=mass/molar mass
(3) determine limiting reactant (whichever one you have less of will determine how much product you can make)
(4) use the coefficients from the balanced equation to find how many moles of product you make
(5) convert to grams ...again using n=m/M
do these and ill help you if you get stuck
im stuck...im trying to convert the grams of the reactant to moles of reactant but im confused
okay, so you know how many grams you have .. do you know each reactants molar mass?
molar mass of C=12.011?
Molar mass of CS2=76.141
okay so use the formula n=m/M
moles = mass / molar mass
find the number of moles ie. divide the mass by the molar mass
