Solution
The correct option is D 26.7
ANS; DApproximate atomic mass = 26.89 equivalent mass = 8.9 n- factor = $\dfrac{26.89}[8.9} = 3.02 i.e. = 3exact atomic mass = 3×8.9 = 26.7
ANS; D
Approximate atomic mass = 26.89 equivalent mass = 8.9
n- factor = $\dfrac{26.89}[8.9}
= 3.02 i.e. = 3
exact atomic mass = 3×8.9 = 26.7
