Water (H2O) is made up of molecules with a bent structure, whereas hydrogen sulfide (H2S) is
also made up of molecules with a bent structure. Why is the melting point of H20 much higher
than the melting point of H2S? Select all correct answers.
a. The intermolecular forces in H2S are much greater than those in H2O
b. The intermolecular forces in H20 are much greater than those in H2S
c. The three-dimensional arrangement of water makes it a polar molecule
d. Hydrogen sulfide has a lower molar mass than water

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.
