This is a multi-step problem. 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) + 1 HCI(aq) →2 KCI(aq) + CO2(g) + H20(1)

This is a multi-step problem. 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.
