Question

How many moles of BaSO4 are formed if 0.5 moles of Na2SO4 react with excess BaCl2?
Na2SO4 + BaCl2 → BaSO4 + 2NaCl

A. 0.144 mol
B. 0.75 mol
C. 0.5 mol
D. 0.25 mol
GPT 3.5
C. 0.5 mol

From the balanced chemical equation, we can see that the mole ratio between Na2SO4 and BaSO4 is 1:1. Therefore, if 0.5 moles of Na2SO4 react, then 0.5 moles of BaSO4 will be formed.
