Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.

If your numbers are precise but inaccurate, does it mean it might have been instrumental error? For my lab, I got an average of 8% error, all numbers close to each other. A question asks which was the possible major source of error. Since the numbers are precise but inaccurate, would this mean it is more likely an instrumental error? One of the scales only read two sig figs, which would make it more inaccurate overall. it was for ideal gas. %rsd: 5.08 std: 0.0043

The average kinetic energy of the molecules in a gas sample depends only on the temperature, T. However, given the same kinetic energies, a lighter molecule will move faster than a heavier molecule, as shown in the equation for rms speed 3 RT rms speed %3D where R = 8.314 J/(mol-K) and M is molar mass in kilograms per mole. Note that a joule is the same as a kilogram-meter squared per second squared (kg-m²/s²).
