Calculating Atomic Mass of the Element

There are a few steps to follow in order to calculate the atomic mass of the element based on the given information:

1. Calculate the molecular weight of the volatile chloride of the metal:
- The vapour density of the volatile chloride is 59.5, which means that its molecular weight is 59.5 times the weight of hydrogen (since hydrogen is the reference element for vapour density).
- The weight of hydrogen is 1 atomic mass unit (amu), so the molecular weight of the volatile chloride is 59.5 amu.

2. Determine the formula of the volatile chloride:
- The equivalent mass of the metal is 24, which means that 1 mole of the metal combines with 2 moles of chlorine (since chlorine has an equivalent weight of 35.5).
- Therefore, the formula of the volatile chloride is MCl2 (where M is the metal).

3. Calculate the atomic mass of the metal:
- The molecular weight of the volatile chloride (59.5 amu) is equal to the sum of the atomic weight of the metal (M) and twice the atomic weight of chlorine (Cl):
- 59.5 = M + 2(35.5)
- 59.5 = M + 71
- M = -11.5
- The negative value for M is not possible, so we must conclude that there is an error in the given information.

Conclusion

Based on the given information, it is not possible to calculate the atomic mass of the element. The negative value obtained in Step 3 indicates that there is an error either in the vapour density or the equivalent mass of the metal.

By using formula 2 * VD/ Equ weight + molar mass of chloride
we will get ans
