Avogadro's number (Equation ) like any pure number, is dimensionless. However, it also defines the mole, so we can also express NA as 6.02 × 1023 mol–1; in this form, it is properly known as Avogadro's ...

WebAnswer (1 of 3): The diameter of an atom is on the order of 10 to the negative 10 m. The order means plus or minus a factor of 10. That's a larger uncertainty than most people expect when doing calculations but this is an approximation calculation. You can look up a more accurate value if you lik... WebAnswer: Depends on the definition of “radius”: Half the distance of two carbons in diamond - 77 pm. In this model the atoms are spheres without overlap, as common in crystallography. Van der Waals’ radius - ca. 170 pm. That is half of the nearest distance two unbound carbons can have. Size of ... immigration office aalen
