Answer
130 amu
Work Step by Step
Isopentyl acetate contains the following molecules with such molecular weights:
7 Carbon atoms- 12 amu each
14 Hydrogen atoms- 1 amu each
2 Oxygen atoms- 16 amu each
When the number of atoms are multiplied with their corresponding atoms the result is:
84amu Carbon + 14 amu Hydrogen + 32 amu Oxygen
=130 amu of isopenyl acetate
