What is the molar mass of C4H8O2?

Understand the Problem

The question is asking for the calculation of the molar mass of the chemical compound C4H8O2. To solve this, we will determine the molar mass by adding the atomic masses of all the atoms in the molecular formula.

Answer

88.12 g/mol

Steps to Solve

Identify the Atoms in the Compound

The molecular formula C$_4$H$_8$O$_2$ consists of the following atoms:

Carbon (C): 4 atoms
Hydrogen (H): 8 atoms
Oxygen (O): 2 atoms

Find the Atomic Masses of Each Element

Next, we need to know the atomic masses of each element (in grams per mole):

Carbon (C) = 12.01 g/mol
Hydrogen (H) = 1.01 g/mol
Oxygen (O) = 16.00 g/mol

Calculate the Total Mass for Each Element

Now, multiply the number of atoms of each element by its respective atomic mass:

Carbon: $4 \times 12.01 = 48.04$ g/mol
Hydrogen: $8 \times 1.01 = 8.08$ g/mol
Oxygen: $2 \times 16.00 = 32.00$ g/mol

Add the Masses Together

Finally, add the total masses of all the elements to find the molar mass of the compound: $$ \text{Total Molar Mass} = 48.04 + 8.08 + 32.00 $$

Calculate the Final Molar Mass

Perform the addition: $$ \text{Total Molar Mass} = 48.04 + 8.08 + 32.00 = 88.12 , \text{g/mol} $$

The molar mass of the compound C$_4$H$_8$O$_2$ is 88.12 g/mol.

More Information

The molar mass is an important property in chemistry that helps in converting between the mass of a substance and the amount in moles. This calculation is fundamental for stoichiometry in chemical reactions.

Tips

Forgetting to multiply the atomic mass by the number of atoms for each element.
Miscalculating the total mass when adding up the contributions from each element.
Using incorrect atomic masses from memory; it's always good to check a reliable source.
