Answer: It has to be 56.10564
Explanation:1 grams KOH to mol = 0.01782 mol
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
200 grams KOH to mol = 3.5647
Answer: 1.22mol
Explanation:
MM of KOH = 39 + 16 + 1 = 56g/mol
Mass conc. Of KOH = 68.5g
Number of mole = Mass conc. / MM
Number of mole = 68.5/56 = 1.22mol
