I think its cubic meters....
Answer:
0.744 mol
Explanation:
the balanced equation for the reaction is
8Fe + S₈ ---> 8FeS
molar ratio of Fe to S₈ is 8:1
number of moles of Fe - 55.0 g / 56 g/mol = 0.98 mol
number of moles of S - 23.8 g / 256 g/mol = 0.093 mol
if we are to assume that S₈ is the limiting reactant
if 1 mol of S₈ reacts with 8 mol of Fe
then 0.093 mol of S₈ reacts with - 8 x 0.093 mol = 0.744 mol of Fe
however there's 0.98 mol of Fe present but only 0.744 mol of Fe is needed
therefore Fe is in excess and S₈ is the limiting reagent
molar ratio of S₈ to FeS is 1:8
then 0.093 mol of S₈ reacts with - 8 x 0.093 = 0.744 mol of FeS
number of FeS moles produced is 0.744 mol
Extensive property (like volume and mass), can be measured.
