In the following reaction between carbon and sodium sulfate
Na2SO4 + 2C => Na2S + 2 CO2
How many grams of carbon will be consumed in the reaction with 3.00 grams of sodium sulfate (Mm=142.04g/mol)?
Expert Answer
Answer
the reaction is Na2SO4+2C——-> Na2S+2CO2
1mole of Na2SO4 requires 2 moles of C
moles of Na2SO4 in 3 gm= mass of Na2SO4/ molar mass= 3/142.04= 0.021
Moles of C = 2*0.021= 0.042
atomic weight of C= 12, mass of C= moles of C* atomic weight= 0.504 gm of carbon
