Question

An average of 35.35 mL of EDTA solution was required to titrate 50.0 mL aliquots of a standard that contained 0.9682 g of MgCO3 (84.314 g/mol) per liter. What is the molarity of the EDTA solution. Write your answer up to four decimal places and do not write the unit.

Step 1

0 mL aliquot. Moles of MgCO3 = mass (g) / molar mass (g/mol) = 0.9682 g / 84.314 g/mol = 0.01148 mol However, this is the moles of MgCO3 in 1 liter. Since we only have a 50.0 mL aliquot, we need to adjust this value. Moles of MgCO3 in 50.0 mL = 0.01148 mol * Show more…
