10 grams KOH to mol = 0.17824 mol

20 grams KOH to mol = 0.35647 mol

30 grams KOH to mol = 0.53471 mol

40 grams KOH to mol = 0.71294 mol

50 grams KOH to mol = 0.89118 mol

100 grams KOH to mol = 1.78235 mol

MM of KOH = 39 + 16 + 1 = 56g/mol

Mass conc. Of KOH = 68.5g

Number of mole = Mass conc. / MM
