Question

if excess chlorine is added to 5.00 mL of 0.250 M H^2SO^4 what is the theoretical yield

Answer 1

number of moles of $H_2SO_4$ used = morality $\times$ volume $=5/1000\times 0.250=0.00125moles$

$H_2SO_4(aq)+HCl(aq) \to H_2SO_4(aq)+HCl(g)$

mole ratio =1:1

therefore; moles of sulfuric acid and hydrochloride gas produced is 0.00125 each.
