Gas powered Weed Eater trimmers that produce a fuel smell but won't start, may have a flooded engine. Set the trimmer aside for 10 to 15 minutes to allow the fuel to vaporize, and then simultaneously squeeze the throttle trigger and pull the starter rope handle repeatedly until the engine starts and runs.
Avogadro's number definition, the constant, 6.022 Ã 10 23 , representing the number of atoms, molecules, or ions in one mole of a substance. Symbol: N. See more.
Avogadro's number can be determined experimentally by observing the actual mass (usually via the momentum) of a single atom or molecule, then comparing that to the mass of one gram-molecular-weight (or mole) of the same substance. One mole of any element is equal to its atomic weight in grams.
