Answer:

4 x 12 +9 x 1= 56

Explanation:

I do not know what the 114.17 g/mol comes from

Answer: The molar mass of [tex]C_4H_9[/tex] is 57.134 g/mol

Explanation:

Molar mass is defined as the sum of the mass of all the atoms each multiplied its atomic masses that are present in the molecular formula of a compound. It is expressed in g/mol.

We are given:

A chemical compound having molecular formula [tex]C_4H_4[/tex]

We know that:

Molar mass of carbon = 12.011 g/mol

Molar mass of hydrogen = 1.01 g/mol

Molar mass of [tex]C_4H_9=(4\times 12.011)+(9\times 1.01)=57.134g/mol[/tex]

Hence, the molar mass of [tex]C_4H_9[/tex] is 57.134 g/mol
