Calculating Physical Quantities for C4H10

Let's calculate the key physical quantities for the proposed compound C4H10, which has the molecular formula (C4H10).

The molar mass of C4H10 is 58.12 g/mol. To calculate this, we take the mass of one carbon atom (12.011 g/mol), multiply it by the 4 carbon atoms in the molecule, and add that to the mass of one hydrogen atom (1.008 g/mol) multiplied by the 10 hydrogen atoms.

One mole of C4H10 occupies 58.12 grams of the substance. Since 1 mole of any substance corresponds to its molar mass in grams, and the molar mass of C4H10 is 58.12 g/mol, then 1 mole of C4H10 must occupy 58.12 grams.

The molecular weight of C4H10 is 58.12 g. This is simply another way to state the molar mass, which gives the total weight in grams of one molecular unit/formula unit of the substance.

One mole of C4H10 contains 6.022x1023 molecular/formula units. This follows from Avogadro's number, which tells us that one mole of any pure substance contains 6.022x1023 elementary entities, whether they are atoms, molecules, ions or formula units. Since C4H10 is made of C4H10 molecules/formula units, one mole would contain 6.022x1023 of these units.
