Question 2

An element has two isotopes:
Isotope A: mass = 10 u, abundance = 20%
Isotope B: mass = 11 u, abundance = 80%
Calculate its relative atomic mass.

//

Satu unsur mempunyai dua isotop:
Isotop A: jisim = 10 u, kelimpahan = 20%
Isotop B: jisim = 11 u, kelimpahan = 80%
Hitungkan jisim atom relatifnya.
