WebLet's examine proportional factors that we have. 1.) The attractive force is proportional to the density of molecules (the more molecules we have, the stronger the force), hence proportional to n/V. 2.) On the same time not all molecules experience the same attractive forces. As it was said in the video, the attractive forces between the ... WebFeb 14, 2024 · 88.8%. Molecular weight is the mass of a molecule of a substance. It can also be called molecular mass. The units for molecular weight are atomic mass units (amu). Molar mass is the mass of one …
WebOne mole of a substance is equal to 6.022 × 10²³ units of that substance (such as atoms, molecules, or ions). The number 6.022 × 10²³ is known as Avogadro's number or … WebImagine our gas molecules bouncing around in the container. The pressure we measure comes from the force of the gas molecules hitting the walls of the container. Attractive forces between the molecules will pull them a little closer together, which effectively slows the molecule down a little before it hits the container wall.
WebThis formula can be written as: Number of Atoms or Molecules = (Number of Moles)* (6.022*1023) The relationship between the atomic mass unit (amu) and the gram is given by: 1 amu = (1gram)/ (6.022*1023) = … WebWhat is the mole and Avogadro's constant?
