Question

A sample of 2.25 gram of standard sodium carbonate (Na2CO3) was used to standardized .17 unknown concentration of HCl acid. The titration of the sample of sodium carbonate required 25.9 ml of HCl acid. Calculate the concentration of HCl acid? (Molar mass of Na2CO3 = 106 g/mole) Na2CO3 + 2HCl ? Products g/mole 1.112 g/mole 0.876 g/mole 1.502 g/mole 1.638

Step 1

Given mass of Na2CO3 = 2.25 grams Molar mass of Na2CO3 = 106 g/mol Number of moles = Mass / Molar mass Number of moles = 2.25 g / 106 g/mol Number of moles = 0.0212 mol Show more…
