Science / Chemistry / Avogadro: Italian chemist and physicist Amadeo Avogadro (1776-1856) proposed a correct molecular explanation for Gay-Lussac's law of combining volumes. His work provided a simple way to determine atomic weights and molecular weights of gases.

Avogadros Law

Science / Chemistry / Avogadros Law: Equal volumes of an ideal gas contain equal numbers of molecules, if both volumes are at the same temperature and pressure. For example, 1 L of ideal gas contains twice as many molecules as 0.5 L of i MORE

Avogadro Number (Na, L)

Science / Chemistry / Avogadro Number (Na, L): The number of particles in one mole, equal to 6.02214199 × 1023 mol-1 (± 0.00000047 mol-1) [1998 CODATA values]. MORE

Boltzmann Constant

Science / Chemistry / Boltzmann Constant: A fundamental constant equal to the ideal gas law constant divided by Avogadro's number, equal to 1.3805 × 10-23 J K-1. MORE


Science / Biology / Mole: Avogadros number (6.02 X 1023 atoms) of a substance. MORE
