Question

carbon has three isotopes. the percentage ambulance of these isotopes is in ratio 98%:1.2%:0.8% calculate the the relative atomic weight of carbon​

Answer 1

Average atomic mass = F

1 M 1 +F 2 M 2 +...+F nM n

Where F

1 ,F 2 ,...F n

is the fraction representing the natural abundance of the isotope and M is the weight of the isotope.

Avg. At. Mass = (0.85×11)+(0.10×12)+(0.05×13)

= 9.35+1.2+0.65

Therefore, the average atomic mass = 11.2
