Given density, what is the method to find molarity? Correct Answer: p = m/v ... solve for m ... find mol by multiplying m x mol/m (molar mass which should be given)... plug in mol into M = mol / L of solution! What are the properties of a water molecule? Correct Answer: The bent structure of the water molecule and ratio of covalently-bonded hydrogens to lone pairs of electrons on the oxygen atom maximizes the hydrogen bonding that occurs in the solid phase, producing a hexagonal structure w...
