Why do polar compounds tend to have higher melting boiling points than nonpolar compounds?

Agood hypothesis includes which of the following? a: prediction b: data c: uncertainty d: conclusion

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.

Suppose you wanted to make 100 grams of water. what is the molar mass of water (h2o)?
