Question

if the atomic mass of carbon were set to be 50 amu , what would be the value of avogadro 's number ​

Answer 1

Answer:

If the atomic mass of carbon were set to be 50 amu, then the value of Avogadro's number would be 2.5×10²⁴.

Explanation:

Given,

      the atomic mass of C = 50amu

     mass of one ¹²C atom = 12 / 6.02×10²³ g =  1.994 x 10⁻²³ g

mass of a single atom given by,

mass of one atom = atomic mass / Avogadro's number

then,

Avogadro's number =  atomic mass  /mass of one atom

⇒                               = 50 / 1.994 x 10⁻²³ = 2.5×10²⁴

Hence, Avogadro's number on this scale is 2.5×10²⁴
