Question

Neon has two isotopes neon-20 and neon-22 given abundances 90 %and 10% resp , find the average atomic mass of beon

Answer 1

Answer:

Explanation:

This simply can be explained as below Ne (avg at. Mass)=(Ne -20 has a mass of 19.9924 amu , also Ne -22 has a mass of 21.9914amu & relative ambundances are

20Ne is 90% &22 Ne is 10% so avg at.mass of Ne is=(19.9924×90%)+(21.9914×10%)=20.1923 amu.
