How many grams are in 1.52 moles of PC13? (molar mass: 137.33 g/mol)

Determine the number o moles of ions/atoms/particle in the following: 2.50 miles of k2s (let me know how to do)

What shape would a molecule with two bound groups and two lone pairs have?

You just calculated that the heat of fusion for chloromethane is 6400 j/mol. the heat of fusion for hydrogen is 120 j/mol.? which of the following account for this difference? more than one correcta. chloromethane can absorb more energy at the same temperature. b. hydrogen has stronger intermolecular forces than chloromethane. c. hydrogen molecules can pack more closely than chloromethane molecules. d. chloromethane experiences dipole-dipole interactions. e. chloromethane has a higher molar mass than hydrogen.
