This question has multiple parts. Work all the parts to get the most points Sodium sulfide, NazS, is used in the leather industry to remove hair from hides. The NazS is made by the reaction Na2SO4(s) + 4 C(s) Na2S(s) + 4 CO(g). Suppose you mix 19.0 g of Na)SO, and 6.30 g of C. What mass of Na)S is produced? g NaS Submit Subimit Answer Try Another Version 3 item attempts remaining

Solution

moles of Na2So4 = 19 g / 142 (g/mol) = 0.1338 mol

moles of C = 6.3 g / 12 (g/mol) = 0.525 mol

now

consider the balanced reaction

Na2SO4 + 4 C ---> Na2S + 4 CO

now

moles of C required = 0.1338 mol Na2SO4 x 4 mol C / 1 mol Na2SO4

moles of C required = 0.5352 mol C

only

0.525 mol C are present

so C is the limiting reagent

now

moles Na2S produced = 0.525 mol C x 1 mol Na2S / 4 mol C

moles Na2S produced = 0.13125 mol

now

mass of Na2S produced = 0.13125 mol x 78 g / mol

mass of Na2S produced = 10.2375 g

so

10.2375 g Na2S is produced
