Chapter 3, Problem 3.33QP

(a)

Interpretation Introduction

Interpretation: Molar mass of the given flavoring additive 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 flavoring additive molecule vanillin C8H8O3 .

Answer to Problem 3.33QP

Solution

The molar mass of the C8H8O3 molecule is 152.417g/mol_ .

Explanation of Solution

Explanation

The given C8H8O3 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 C8H8O3 molecule is calculated by the given formula,

MC8H8O3=8MC+8MH+3MO

Where,

  • MC8H8O3 represents the molar mass of the C8H8O3 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.

MC8H8O3=8MC+8MH+3MOMC8H8O3=8(12.0107g/mol)+8(1.0079g/mol)+3(15.9994g/mol)MC8H8O3=(96.0856g/mol)+(8.0632g/mol)+(47.9982g/mol)MC8H8O3=152.417g/mol_

Answer to Problem 3.33QP

Solution

The molar mass of the C10H12O2 molecule is 164.2006g/mol_ .

Explanation of Solution

Explanation

The given C10H12O2 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 C10H12O2 molecule is calculated by the given formula,

MC10H12O2=10MC+12MH+2MO

Where,

  • MC10H12O2 represents the molar mass of the C10H12O2 molecule.

Substitute the values in the above formula.

MC10H12O2=10MC+12MH+2MOMC10H12O2=10(12.0107g/mol)+12(1.0079g/mol)+2(15.9994g/mol)MC10H12O2=164.2006g/mol_

Answer to Problem 3.33QP

Solution

The molar mass of the C10H12O molecule is 149.2012g/mol_ .

Explanation of Solution

Explanation

The given C10H12O 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 C10H12O molecule is calculated by the given formula,

MC10H12O=10MC+12MH+MO

Where,

  • MC10H12O represents the molar mass of the C10H12O molecule.

Substitute the values in the above formula.

MC10H12O=10MC+12MH+MOMC10H12O=10(12.0107g/mol)+12(1.0079g/mol)+(15.9994g/mol)MC10H12O=149.2012g/mol_

Answer to Problem 3.33QP

Solution

The molar mass of the C9H8O molecule is 132.1589g/mol_ .

Explanation of Solution

Explanation

The given C9H8O 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 C9H8O molecule is calculated by the given formula,

MC9H8O=9MC+8MH+MO

Where,

  • MC9H8O represents the molar mass of the C9H8O molecule.

Substitute the values in the above formula.

MC9H8O=9MC+8MH+MOMC9H8O=9(12.0107g/mol)+8(1.0079g/mol)+(15.9994g/mol)MC9H8O=132.1589g/mol_

Conclusion

  1. a) The molar mass of C8H8O3 is 152.417g/mol_ .
  2. b) The molar mass of C10H12O2 is 164.2006g/mol_ .
  3. c) The molar mass of C10H12O is 149.2012g/mol_ .
  4. d) The molar mass of C9H8O is 132.1589g/mol_
