Chapter 3, Problem 3.34QP

(a)

Interpretation Introduction

Interpretation: Molar mass of the given sweetener molecules are to be calculated.

Concept introduction: Molar mass is a physical quantity to measure the mass of the atoms. The mass in grams of one mole of any substance is known as the molar mass of that substance. It is represented by the symbol M . In case of molecules the molar mass of the molecule is the sum of molar mass of all the atoms present in that molecule. Generally the molar mass of the compound is expressed in g/mol .

To determine: The molar mass of the sweetener molecule sucrose C12H12O11 .

Answer to Problem 3.34QP

Solution

The molar mass of the C12H12O11 molecule is 332.2202g/mol_ .

Explanation of Solution

Explanation

The given C12H12O11 molecule consists of one manganese atom, one silicon atom and three oxygen atoms.

Therefore, the molar mass of the given molecule is the sum of all the atoms present in the molecule.

The molar mass of the carbon, hydrogen and oxygen atoms are 12.0107g/mol,1.0079g/moland15.9994g/mol respectively. Hence, the molar mass of the C12H12O11 molecule is calculated by the given formula,

MC12H12O11=12MC+12MH+11MO

Where,

  • MC12H12O11 represents the molar mass of the C12H12O11 molecule.
  • MC represents the atomic mass of the C atom.
  • MH represents the atomic mass of the H atom.
  • MO represents the atomic mass of the O atom.

Substitute the values in the above formula.

MC12H12O11=12MC+12MH+11MOMC12H12O11=12(12.0107g/mol)+12(1.0079g/mol)+11(15.9994g/mol)MC12H12O11=(144.1284g/mol)+(12.0948g/mol)+(175.9934g/mol)MC12H12O11=332.2202g/mol_

Answer to Problem 3.34QP

Solution

The molar mass of the C7H5NO3S molecule is 164.2006g/mol_ .

Explanation of Solution

Explanation

The given C7H5NO3S molecule consists of one calcium atom, one tungsten atom and four oxygen atoms.

Therefore, the molar mass of the given molecule is the sum of all the atoms present in the molecule.

Hence, the molar mass of the C7H5NO3S molecule is calculated by the given formula,

MC7H5NO3S=7MC+5MH+MN+3MO+MS

Where,

  • MC7H5NO3S represents the molar mass of the C7H5NO3S molecule.
  • MN represents the atomic mass of the N atom.
  • MS represents the atomic mass of the S atom.

Substitute the values in the above formula.

MC7H5NO3S=7MC+5MH+MN+3MO+MSMC7H5NO3S=[7(12.0107g/mol)+5(1.0079g/mol)+(14.0067g/mol)+3(15.9994g/mol)+(32.0650g/mol)]MC7H5NO3S=183.1800g/mol_

Answer to Problem 3.34QP

Solution

The molar mass of the C14H18N2O5 molecule is 294.3012g/mol_ .

Explanation of Solution

Explanation

The given C14H18N2O5 molecule consists of one iron, one titanium and three oxygen atoms.

Therefore, the molar mass of the given molecule is the sum of all the atoms present in the molecule.

Hence, the molar mass of the C14H18N2O5 molecule is calculated by the given formula,

MC14H18N2O5=14MC+18MH+2MN+5MO

Where,

  • MC14H18N2O5 represents the molar mass of the C14H18N2O5 molecule.

Substitute the values in the above formula.

MC14H18N2O5=14MC+18MH+2MN+5MOMC14H18N2O5=(14(12.0107g/mol)+18(1.0079g/mol)+2(15.0100g/mol)+5(15.9994g/mol))MC14H18N2O5=294.3012g/mol_

Answer to Problem 3.34QP

Solution

The molar mass of the C6H12O6 molecule is 180.1607g/mol_ .

Explanation of Solution

Explanation

The given C6H12O6 molecule consists of one magnesium atom, one carbon atom and three oxygen atoms.

Therefore, the molar mass of the given molecule is the sum of all the atoms present in the molecule.

Hence, the molar mass of the C6H12O6 molecule is calculated by the given formula,

MC6H12O6=6MC+12MH+6MO

Where,

  • MC6H12O6 represents the molar mass of the C6H12O6 molecule.

Substitute the values in the above formula.

MC6H12O6=6MC+12MH+6MOMC6H12O6=6(12.0107g/mol)+12(1.0079g/mol)+6(15.9994g/mol)MC6H12O6=180.1607g/mol_

Conclusion

  1. a) The molar mass of the C12H12O11 is 332.2202g/mol_ .
  2. b) The molar mass of the C7H5NO3S is 183.1800g/mol_ .
  3. c) The molar mass of the C14H18N2O5 is 294.3012g/mol_ .
  4. d) The molar mass of the C6H12O6 is 180.1607g/mol_
