compared to h₂s, the higher boiling point of h₂o is due to the
○ greater molecular size of water
○ stronger hydrogen bonding in water
○ higher molarity of water
○ larger gram formula mass of water

Explanation:

Hydrogen bonding in water is stronger than in $H_2S$. It takes more energy to break these bonds, resulting in a higher boiling - point for water. Molecular size, molarity, and gram - formula mass are not the main reasons for the difference in boiling points here.

Answer:

B. stronger hydrogen bonding in water
