An organic acid is composed of carbon (68.84%), hydrogen (4.96%), and oxygen (26.20%). Its molar mass is 122.12 g/mol. Determine the molecular formula of the compound.

The molecular formula of the compound is .

Explanation:

Let consider that given percentages are mass percentages, so that mass of each element are determined by multiplying molar massof the organic acid by respective proportion. That is:

Carbon

Hydrogen

Oxygen

Now, the number of moles (), measured in moles, of each element are calculated by the following expression:

Where:

- Mass of the element, measured in grams.

- Molar mass of the element, measured in grams per mol.

Carbon (, )

Hydrogen (, )

Oxygen (, )

For each mole of organic acid, there are 7 moles of carbon, 6 moles of hydrogen and 2 moles of oxygen. Hence, the molecular formula of the compound is:

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
