A 0.3126 g sample of h2c2o4 requires 26.21 ml of parcular concentraon of NaOH to complete the
following reacon. what is the molarity of NaOH
Molarity = moles of solute
Liters of soluon
Soluons are made of solutes and solvents.
Solutes are dissolved material
Solvents are the dissolving material
