Chapter 4, Problem 4.37E
Interpretation Introduction

(a)

Interpretation:

The formula weight in atomic mass units for the given binary ionic compound is to be determined.

Concept introduction:

Ionic compounds are those compounds that have the strong electrostatic force of attraction between the oppositely charged ions. A huge amount of heat is required to separate these oppositely charged ions. Therefore, the melting point of ionic solids is high.

Answer to Problem 4.37E

The formula weight in atomic mass units for the given binary ionic compound is 61.98u.

Explanation of Solution

The formula weight of binary compounds is the sum of atomic weight of each atom.

The formula weight of Na2O is calculated by the formula,

Formulaweight=(2×atomicweightofNa)+(1×atomicweightofO) …(1)

The atomic weights of Na and O are 22.99u and 16.0u, respectively.

Substitute the atomic weight of Na and O in equation (1).

Formulaweight=(2×22.99u)+(1×16.0u)=(45.98+16.0)u=61.98u

Conclusion

The formula weight in atomic mass units for the given binary ionic compound is 61.98u.

Answer to Problem 4.37E

The formula weight in atomic mass units for the given binary ionic compound is 71.85u.

Explanation of Solution

The formula weight of binary compounds is the sum of atomic weight of each atom.

The formula weight of FeO is calculated by the formula,

Formulaweight=(1×atomicweightofFe)+(1×atomicweightofO) …(2)

The atomic weights of Fe and O are 55.85u and 16.00u, respectively.

Substitute the atomic weight of Fe and O in equation (2).

Formulaweight=(1×55.85u)+(1×16.00u)=71.85u

Conclusion

The formula weight in atomic mass units for the given binary ionic compound is 71.85u.

Answer to Problem 4.37E

The formula weight in atomic mass units for the given binary ionic compound is 271.32u.

Explanation of Solution

The formula weight of binary compounds is the sum of atomic weight of each atom.

The formula weight of PbS2 is calculated by the formula,

Formulaweight=(1×atomicweightofPb)+(2×atomicweightofS) …(3)

The atomic weights of Pb and S are 207.2u and 32.06u, respectively.

Substitute the atomic weight of Pb and S in equation (3).

Formulaweight=(1×207.2u)+(2×32.06u)=207.2u+64.12u=271.32u

Conclusion

The formula weight in atomic mass units for the given binary ionic compound is 271.32u.

Answer to Problem 4.37E

The formula weight in atomic mass units for the given binary ionic compound is 133.28u.

Explanation of Solution

The formula weight of binary compounds is the sum of atomic weight of each atom.

The formula weight of AlCl3 is calculated by the formula,

Formulaweight=(1×atomicweightofAl)+(3×atomicweightofCl) …(4)

The atomic weights of Al and Cl are 26.93u and 35.45u, respectively.

Substitute the atomic weight of Al and Cl in equation (4).

Formulaweight=(1×26.93u)+(3×35.45u)=26.93u+106.35u=133.28u

Conclusion

The formula weight in atomic mass units for the given binary ionic compound is 133.28u.
