Use the formula of molarity and the balanced equation to determine the volume of 1.50 M HCl needed to react with 0.50 L of 0.20 M Na2CO3
Step 1. Establish the dimensional analysis for the solution stoichiometry
Hydrochloric acid HCl reacts with sodium carbonate Na 2CO3, forming sodium chloride NaCl, water H2O, and carbon dioxide CO2. This equation is balanced as written:
2HCl(aq) + Na2CO3(aq) = 2NaCl(aq) + H2O(l) + CO2(g)
What volume of 1.50 M HCl in liters is needed to react completely (with nothing left over) with 0.500 L of 0.200 M Na2CO3? Express your answer numerically in liters.
