Round your answer to 2
significant figures.
The equation is below:
H2SO4(aq) + 2NaOH(s) --> Na2SO4(aq) + 2H2O(l).
The limiting reactant should be determined first.
According to the equation, NaOH and H2SO4 react in 2:1 molar ratio.
, hence H2SO4 is the limiting reactant.
Now the theoretical yield of Na2SO4 can be calculated:
Answer: 83%
