Question

Atomic weight of ne is 20.2. Ne is modure of ne and ne relative abundance of heavier isotope is

Answer 1

Answer:

From the atomic weight tables, the atomic weight of neon = 20.2. Therefore 20.2 g of neon contains 6.022 × 1023 Ne atoms. By proportion, 10.1 g of neon contains 10.1 × 6.022 × 1023 Ne atoms 20.2 = 3.011 × 1023 Ne atoms.

Answer 2

Answer:

10%

Explanation: Dear Student

          Ne20 = x

          Ne22 =100-x

20.2   = [ 20(x) +22(100-x)]/100

2020 = 20x+2200-22x

2x      = 2200-2020

2x     =180

   x    =90%

Ne22 = 100-x = 10%

Hope it helps
