Predict which will have the higher boiling point: N 2 or CO. Explain your reasoning. Solution. CO and N 2 are both diatomic molecules with masses of about 28 amu, so they experience similar London dispersion forces. Because CO is a polar molecule, it experiences dipole-dipole attractions.
We will look at what a molar ratio is and then a brief word on how to recognize which ratio to use in a problem. The ChemTeam's favorite sample equation is: I will use it for the first three examples. Example #1: What is the molar ratio between H 2 and O 2? The ratio is two-to-one.
This online calculator can calculate the molar concentration of a solute in a solution, or mass of a solute in a solution with a specific molar concentration.
When the coefficients from the balanced chemical equation are used to represent conversion factors in terms of the number of moles, the relationships are called molar ratios.
