Problem Page What kind of intermolecular forces act between a formaldehyde molecule and a hydrogen sulfide molecule? Note: If th
ere is more than one type of intermolecular force that acts, be sure to list them all, with a comma between the name of each force. Clears your work. Undoes your last action. Provides information about entering answers.
Formaldehyde, H2CO, has an oxygen atom which is quite electronegative that means it would attract any atom with a slightly positive charge. Hydrogen in the Hydrogen sulfide (H2S) is attracted by oxygen and hence hydrogen bonding can occur.
Using the mass/volume percentage method for percentages of the solution, you simply divide the grams of solute by the volume of the solution and multiply by 100 to get your percentage. (75.0g/250mL)•100 = 30.0% solute
