Neon atoms are known to produce a mass spectrum that consists of three peaks at m/z values of 20, 21 and 22, with the relative a

bundance of the peaks found to be in the ratio 112:0.21:11.1. Assuming the z value of the species causing the peaks to be +1 in each case, calculate the average atomic mass of neon based on these data.

Answer:

Explanation:

m / z = 20 , 21 , 22

m / 1 = 20 , 21 , 22

m = 20 , 21 , 22 .

ratio of isotopes = 112 : 0.21 : 11.1

Average atomic mass = (112 x 20 + .21 x 21 + 11.1 x 22) / (112 + .21 + 11.1 )

= (2240 + 4.41 + 244.2) / 123.31

= 2488.61 / 123.31

= 20.18
