Answer to Problem E.23E

Moles of Cu2+ present in 3.00g of CuBr2 is 0.0134mol.

Explanation of Solution

The mass of copper(II) bromide is given as 3.00g.  The molar mass of CuBr2 is calculated as follows;

    Molarmass=M(Cu)+2×M(Br)=63.55gmol1+2(80.00gmol1)=223.55gmol1

Therefore, for copper(II) bromide, 223.55gmol1 is the molar mass.  Number of moles of copper(II) bromide present in 3.00g can be calculated as follows;

    Numberofmoles=MassofCuBr2MolarmassofCuBr2=3.00g223.55gmol1=0.0134mol

One mole of copper(II) bromide contains one mole of Cu2+ ions.  Therefore, the moles of Cu2+ ions in 0.0134mol of copper(II) bromide is calculated as shown below;

    MolesofCu2+=0.0134mol×1molCu2+1molCuBr2=0.0134mol

Thus the moles of copper(II) ion present in 3.00g of copper(II) bromide is 0.0134mol.

Interpretation Introduction

Interpretation:

The amount of SO3 molecules in moles has to be calculated that is present in 7.00×102mg of SO3.

(b)

Expert Solution

Answer to Problem E.23E

Moles of SO3 present in 7.00×102mg of SO3 is 0.0087mol.

Explanation of Solution

The mass of sulfur trioxide is given as 7.00×102mg.  The molar mass of SO3 is calculated as follows;

    Molarmass=M(S)+3×M(O)=32.06gmol1+3(16.00gmol1)=80.06gmol1

Therefore, for sulfur trioxide, 80.06gmol1 is the molar mass.  Number of moles of SO3 present in 7.00×102mg can be calculated as follows;

    Numberofmoles=MassofSO3MolarmassofSO3=7.00×102mg80.06gmol1=0.700g80.06gmol1=0.0087mol

Thus the moles of sulfur trioxide present in 7.00×102mg of sulfur trioxide is 0.0087mol.

(c)

Interpretation Introduction

Interpretation:

The amount of F ions in moles has to be calculated that is present in 25.2kg of UF6.

(c)

Expert Solution
Check Mark

Answer to Problem E.23E

Moles of F present in 25.2kg of UF6 is 430mol.

Explanation of Solution

The mass of UF6 is given as 25.2kg.  The molar mass of UF6 is calculated as follows;

    Molarmass=M(U)+6×M(F)=238.03gmol1+6(18.99gmol1)=351.97gmol1

Therefore, for UF6, 351.97gmol1 is the molar mass.  Number of moles of UF6 present in 25.2kg can be calculated as follows;

    Numberofmoles=MassofUF6MolarmassofUF6=25.2×103g351.97gmol1=71.6mol

Thus the moles of UF6 present in 25.2kg of UF6 is 71.6mol.

One mole of UF6 contains six moles of F ion.  Therefore, the number of moles of F ion present in 25.2kg is calculated as shown below;

    NumberofmolesofF=6×71.6mol=429.6mol=430mol

Therefore, the number of moles of F ion present in 25.2kg of UF6 is 430mol.

(d)

Interpretation Introduction

Interpretation:

The amount of H2O in moles has to be calculated that is present in 2.00g of Na2CO310H2O.

(d)

Expert Solution
Check Mark

Answer to Problem E.23E

Moles of H2O present in 2.00g of Na2CO310H2O is 0.0087mol.

Explanation of Solution

The mass of Na2CO310H2O is given as 2.00g.  The molar mass of Na2CO310H2O is calculated as follows;

    Molarmass=2×M(Na)+1×M(C)+3×M(O)+10×M(H2O)=2×22.99gmol1+1(12.01gmol1)+3(16.00gmol1)+10(18.00gmol1)=(45.98+12.01+48.00+180.00)gmol1=285.99gmol1

Therefore, for Na2CO310H2O, 285.99gmol1 is the molar mass.  Number of moles of Na2CO310H2O present in 2.00g can be calculated as follows;

    Numberofmoles=MassofNa2CO310H2OMolarmassofNa2CO310H2O=2.00g285.99gmol1=0.007mol

Thus the moles of Na2CO310H2O present in 2.00g of Na2CO310H2O is 0.007mol.

One mole of Na2CO310H2O contains ten moles of H2O molecules.  Therefore, the number of moles of H2O molecule present in 2.00g is calculated as shown below;

    NumberofmolesofH2O=10×0.007mol=0.07mol

Therefore, the number of moles of H2O molecules present in 2.00g of Na2CO310H2O is 0.07mol.
