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 motor oil
Answer
Explanation:
Step1: Understand viscosity - molar mass relation
Viscosity is related to the size and mass of molecules. Larger - mass molecules tend to have stronger intermolecular forces and higher viscosity.
Step2: Compare viscosities
Motor oil is more viscous than gasoline. Since more viscous substances generally have larger - sized and higher - molar - mass molecules for similar chemical compositions, motor oil has a higher average molar mass.
Answer:
motor oil
