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?
Report your answer to 3 significant figures and do not include units.

Best ResponseYou've already chosen the best response.2so 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

Best ResponseYou've already chosen the best response.2okay, so you know how many grams you have .. do you know each reactants molar mass?

Best ResponseYou've already chosen the best response.0Molar mass of CS2=76.141

Best ResponseYou've already chosen the best response.2okay so use the formula n=m/M moles = mass / molar mass find the number of moles ie. divide the mass by the molar mass

Best ResponseYou've already chosen the best response.2so for carbon m=(8.8g)/(12g/mol) = 0.733 mol
