The solution of this problem involves several steps:
1.- Calculate the mass of CS2 using the density.
2.- Calculate the molecular weight of CS2.
3.- Calculate the moles of CS2 , using the mass of CS2 (calculated on Step 1) and the molecular weight of CS2 (calculated on Step 2).
4.- Calculate the moles of Na2CS3 produced in the reaction, using the relation between moles of CS2 and moles of Na2CS3, that is, by using the coefficients of the balanced equation.
5.- Calculate the molecular weight of ...
