Equivalent mass of Na2S2O3-158.Worked Out ExamplesExample 37. Approximate atomic mass of an elementis 26.89. If its equivalent weight is 8.9, find the exact atomicmass of the element. |

Answer» Equivalent weight = atomic weight/ valency Therefore, valency = 26.89/8.9 = 2.99 or 3 Exact atomic weight = equib=valent weight x valency = 8.9 x 3 = 26.7 g Thus the exact atomic weight = 26.7 gm. mass no |
