NEON has 2 ISOTOPES of differing mass and in different proportions shown below. Which option demonstrates how we calculate its relative atomic mass (A_(r)) in g/mol {}^20Ne:91% {}^22Ne:9% ((91+9)times (20+22))/(100)=42 ((91+20)times (9+22))/(100)=7.11 ((91times 9)+(20times 22))/(100)=12.6 ((91times 20)+(9times 22))/(100)=20.2
