Question

diameter of an atom is 1.8 A what will be the length covered when 1 mole atoms are kept side by side​

Answer 1

Answer:

Length = 10.8396 * 10¹³ m

            = 10.8396 * 10²³ A°

Explanation:

We know that,

Number of moles = $\dfrac{Number \ of \ atoms}{Avogadro \ number}$

Given that,

Number of moles = 1

Avogadro number = 6.022 * 10²³

Substituting these values in we get,

Number of atoms= Number of moles * Avogadro number

Number of atoms = 1 * 6.022 * 10²³

Number of atoms = 6.022 * 10²³

Length covered by 1 atom = 1.8 A°

Length covered ny 6.022 * 10²³ atoms = 1.8 * 6.022 * 10²³

                                                                = 10.8396 * 10²³ A°

                                                                = 10.8396 * 10²³ * 10⁻¹⁰ m

                                                                = 10.8396 * 10¹³ m
