Answer to Problem 4.43E

The number of positive ions and negative ions contained in 1.00mol of Na2O is 12.04×1023 and 6.02×1023 respectively.

Explanation of Solution

The given compound is Na2O.

One mole of Na2O compound contains two moles of Na+ cation and one mole of O2 anion. The number of atoms present in one mole is equal to Avogadro’s number (6.02×1023). Therefore,

The number of Na+ cations is =2×6.02×1023=12.04×1023

The number of O2 anions is =1×6.02×1023=6.02×1023

The number of positive ions and negative ions contained in 1.00mol of Na2O is 12.04×1023 and 6.02×1023 respectively.

Conclusion

The number of positive ions and negative ions contained in 1.00mol of Na2O is 12.04×1023 and 6.02×1023 respectively.

Answer to Problem 4.43E

The number of positive ions and negative ions contained in 1.00mol of FeO is 6.02×1023 and 6.02×1023 respectively.

Explanation of Solution

The given compound is FeO.

One mole of FeO compound contains one mole of Fe2+ cation and one mole of O2 anion. The number of atoms present in one mole is equal to Avogadro’s number (6.02×1023). Therefore,

The number of Fe2+ cations is =1×6.02×1023=6.02×1023

The number of O2 anions is =1×6.02×1023=6.02×1023

The number of positive ions and negative ions contained in 1.00mol of FeO is 6.02×1023 and 6.02×1023 respectively.

Conclusion

The number of positive ions and negative ions contained in 1.00mol of FeO is 6.02×1023 and 6.02×1023 respectively.

Answer to Problem 4.43E

The number of positive ions and negative ions contained in 1.00mol of PbS2 is 6.02×1023 and 12.04×1023 respectively.

Explanation of Solution

The given compound is PbS2.

One mole of PbS2 compound contains one mole of Pb4+ cation and two moles of S2 anion. The number of atoms present in one mole is equal to Avogadro’s number (6.02×1023). Therefore,

The number of Pb4+ cations is =1×6.02×1023=6.02×1023

The number of S2 anions is =2×6.02×1023=12.04×1023

The number of positive ions and negative ions contained in 1.00mol of PbS2 is 6.02×1023 and 12.04×1023 respectively.

Conclusion

The number of positive ions and negative ions contained in 1.00mol of PbS2 is 6.02×1023 and 12.04×1023 respectively.

Answer to Problem 4.43E

The number of positive ions and negative ions contained in 1.00mol of AlCl3 is 6.02×1023 and 18.06×1023 respectively.

Explanation of Solution

The given compound is AlCl3.

One mole of AlCl3 compound contains one mole of Al3+ cation and three moles of Cl anion. The number of atoms present in one mole is equal to Avogadro’s number (6.02×1023). Therefore,

The number of Al3+ cations is =1×6.02×1023=6.02×1023

The number of Cl anions is =3×6.02×1023=18.06×1023

The number of positive ions and negative ions contained in 1.00mol of AlCl3 is 6.02×1023 and 18.06×1023 respectively.

Conclusion

The number of positive ions and negative ions contained in 1.00mol of AlCl3 is 6.02×1023 and 18.06×1023 respectively.

you are to determine the molecular formula for a molecular compound consisting of only carbon & hydrogen. The molar mass of this compound is 42.08 g/mol. Part D: The empirical formula has a molar mass of 14.026 g/mol (this is called the empirical molar mass). Divide the molar mass for the total compound given above by the empirical formula molar mass. This will give you a number for multiplying the carbon atoms and hydrogen atoms in the empirical formula. What is the multiplication value?
Is the formula compound for B the same as for either compound A or C? What’s the molar mass and identity for element X? You are given another sample of compound B, but now it has 1.50moles of copper in it. What’s the total mass of this sample?
