Carbon disulfide is prepared by heating sulfur and charcoal. The chemical equation is S2(g)+C(s)CS2(g)c=9.40 at 900 K S 2 ( g ) + C ( s ) CS 2 ( g ) K c = 9.40 at 900 K How many grams of CS2(g) CS 2 ( g ) can be prepared by heating 18.8 mol S2(g) 18.8 mol S 2 ( g ) with excess carbon in a 8.60 L 8.60 L reaction vessel held at 900 K until equilibrium is attained?
