Water’s molar mass is 18.01 g/mol. the molar mass of glycerol is 92.09 g/mol. at 25°c, glycerol is more viscous than water. which substance has the stronger intermolecular attraction?

glycerol because it is more viscous and has a larger molar mass than water.

Explanation:

Viscosity depends on inter-molecular interactions.

The predominant inter-molecular force in water and glycerol is hydrogen bonding.

Hydrogen bond is an electrostatic attraction between two polar groups in which one group has hydrogen atom (H) and another group has highly electronegative atom such as nitrogen (like in this molecule), oxygen (O) or fluorine (F).

The correct answer is Glycerol.

Explanation:

Liquids with strong intermolecular forces are more viscous than those with weak intermolecular forces.

Viscosity is defined as the flow resistance of a fluid. The greater the intermolecular forces of a liquid, its molecules have more difficulty moving between them, so the substance is more viscous.

Liquids that are made up of long, flexible molecules that can bend and tangle with each other are more viscous.

Have a nice day!
