Question
The equivalent weight of an element is 25. If its specific heat is 0.085 cal/K-g, its exact atomic mass should be
Options
A.75.29
B.75
C.50
D.50.8
Solution
Approximate atomic mass = $\frac{6.4}{0.085} = 75.29$.
Now, Valency = $\frac{\text{Atomic mass}}{\text{Equivalent mass}} \approx \frac{75.29}{25} \approx 3\ \left( \text{integer} \right)$.
∴ Exact atomic mass$= 25 \times 3 = 75$.
