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:

motor oil

Explanation:

According to Oxford dictionary, viscosity refers to ''a quantity expressing the magnitude of internal friction in a fluid, as measured by the force per unit area resisting uniform flow.''

The higher the molecular weight of a substance, the greater its viscosity. This is because, the long chains in the viscous substance become entangled thereby increasing the internal friction in the liquid.

Motor oil is a heavier hydrocarbon than gasoline hence it is more viscous than gasoline.
