Explanation:
Answer:
4.998 × 10²⁴ amu
Explanation:
Given data:
Mass of substance = 8.3 g
Atomic mass unit = ?
Solution:
The mass of one mole of substance is equal the gram per mole of that substance.
atomic mass unit = g/mol
For 8.3 g:
8.3 × 6.022×10²³
4.998 × 10²⁴ amu
The number 6.022 × 10²³ is called Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
