A 0.18 mole sample of nitrogen gas occupies a volume of 2.25L. What is the volume of 0.27 mol of nitrogen gas under the same conditions? A 0.12-mole sample of nitrogen gas occupies a volume of 2.55 L. What is the volume of 0.32 mol of nitrogen gas under the same condit...
The number is derived from international agreement, based on the number of atoms in exactly 12 grams (g) of the carbon isotope "C-12." The convenience this "counting unit," the Avogadro number, provides is seen when considering, for example, the weights of 1 mole each of oxygen, water ...

mole is an abstract number that correlates to 6.02 x 10^23 units of a substance present. It doesn't matter what it is, one mole of it will be 6.02 x 10^23 units. A gram is a scientific measurement of an object's mass. Converting between the two shows us how much a molecule ...
of one mole of any substance normally relates to the individual mass number of the atoms in the substance. For instance, a mole of oxygen boasts a mass of 16 grams, because the most common type of oxygen atom has 8 protons, 8 electrons, 8 neutrons, and accordingly its mass number is ...
