What mass of oxalic acid dihydrate,H₂C₂O₄ · 2H₂O,is required to prepare 220.0 mL of a 1.58 M solution of oxalic acid?

Question

Quizplus · Accepted Answer

To find the mass of oxalic acid dihydrate required, first calculate the moles of oxalic acid needed using the molarity formula (Moles = Molarity × Volume in L). For a 1.58 M solution and 0.220 L, the moles of oxalic acid are 1.58 mol/L × 0.220 L = 0.3476 mol. The molar mass of oxalic acid dihydrate (C2H2O4·2H2O) is approximately 126 g/mol. Therefore, the mass required is 0.3476 mol × 126 g/mol = 43.8 g.
