How do I set up the equation to solve for trail 2?

Part B: Standardizing the diluted KMNO4 solution Calculate: Determine the volume of oxalic acid (H2C204 • 2H20) standard that would use about 15mL of KMNO4 Concentration of given stock oxalic acid (H2C204 • 2H2O) 0.02 Hint- start with 15 mL of your created stock KMNO4 solution moles of KMNO4 to fully react 0.00030 mols moles of oxalic acid (H2C204 ● 2H2O) 0.00075 mols ml of stock oxalic acid (H2C204 • 2H20) 37.50000 mL Calculate the exact Molarity of KMNO4 solution Trial 1 Trial 2 Trial 3 Average Precision Volume (mL) of oxalic acid (H2C2O4 • 2H2O) used 37.09 37.35 37.99 --- --- Volume (mL) of KMNO4 used moles of KMNO4 15.84 16.56 16.66 --- --- 0.000297 --- ---- Exact concentration of KMNO4 0.0187 0.0183
