gasoline and motor oil are chemically similar. they are both mixtures of nonpolar hydrocarbons containing carbon and hydrogen atoms. however, motor oil is much more viscous than gasoline. which substance probably has the higher average molar mass?

gasoline and motor oil are chemically similar. they are both mixtures of nonpolar hydrocarbons containing carbon and hydrogen atoms. however, motor oil is much more viscous than gasoline. which substance probably has the higher average molar mass?

Answer

Explanation:

Step1: Understand viscosity - molar mass relation

Higher molar - mass substances generally have stronger intermolecular forces.

Step2: Relate intermolecular forces to viscosity

Stronger intermolecular forces lead to higher viscosity.

Step3: Compare the two substances

Since motor oil is more viscous than gasoline, it has stronger intermolecular forces.

Step4: Determine the molar - mass

The substance with stronger intermolecular forces (motor oil) probably has a higher average molar mass.

Answer:

Motor oil
