Expert Answer
The percent composition of elements in C4H8O2 is to be calculated.
The percent composition of the elements can be determined from the formula of the compound.
- First, calculate the mass of each element in 1mole of compound.
- Calculate the total molar mass of the compound.
- Then percent composition of each element can be calculated by dividing the mass of each element by the molar mass of the compound and then multiplied by 100.

Mass of element in 1 mole of compound Percent composition of element= Molar mass of compound
Now calculate the mass of C, H and O in 1 mole of C4H8O2-
1 mole of C4H8O2 consists of 4 moles of carbon, 8 moles of Hydrogen and 2 moles of oxygen.
Thus, in C4H8O2
Mass of C = 4×molar mass of C
Mass of H = 8×molar mass of H
Mass of O = 2&...
