KCO3 3. Suppose 36.0246 g of potassium carbonate is dissolved in water to give a final solution volume of 750.0 mL. Now suppose a 50.00 mL sample of a hydrochloric acid solution (concentration unknown) requires 32.06 mL of the potassium carbonate solution to reach the endpoint (complete reaction). What is the molarity of the hydrochloric acid solution? Report your answer with the correct number of significant figures. The unbalanced chemical equation is given below. K2CO3(aq) +2 HCl(aq) → KCI(aq) + CO2(g) + H2O(1)

3. Suppose 36.0246 g of potassium carbonate is dissolved in water to give a final solution volume
of 750.0 mL. Now suppose a 50.00 mL sample of a hydrochloric acid solution (concentration
unknown) requires 32.06 mL of the potassium carbonate solution to reach the endpoint
(complete reaction). What is the molarity of the hydrochloric acid solution? Report your
answer with the correct number of significant figures. The unbalanced chemical equation is
given below.
K2CO3(aq) + HC1(aq) →2 KCI(aq) + CO2(g) +
H20(1)
