Expert Solution
Answer to Problem 111AP
The molar mass of adipic acid (C6H10O4) is 146.1 g/mol.
Explanation of Solution
Molar mass of adipic acid (C6H10O4)
=[6(Atomic mass of C)+10(Atomic mass of H)+4(Atomic mass of O)]=[6(12.01)+10(1.008)+4(15.99)]g/mol=146.1 g/mol
Here,
Atomic mass of carbon = 12.01 g/mol.
Atomic mass of hydrogen = 1.008 g/mol.
Atomic mass of oxygen = 15.99 g/mol.

Expert Solution
Answer to Problem 111AP
The molar mass of vinyl acetate (C4H6O2) is 86.09 g/mol.
Explanation of Solution
Molar mass of vinyl acetate (C4H6O2)
=[4(Atomic mass of C)+6(Atomic mass of H)+2(Atomic mass of O)]=[4(12.01)+6(1.008)+2(15.99)] g/mol=86.09 g/mol
Here,
Atomic mass of carbon = 12.01 g/mol.
