I hope this enlighten. Apologize for any English or Chemistry concepts.
Answer:
207.24.
Explanation:
The mass numbers of the 4 isotopes are 82+ 122 = 204, 82 + 125 = 207,
82 + 124 = 206 and 208.
The approximate atomic mass is worked out by adding the products of their relative abundances and mass numbers:
0.014*204 + 0.221*207 + 0.241*206 + 0.524*208
= 207.24.
You are not belive that many years ago approximate in 1900 century the people made plastic my milk this plasticity then use for making ornaments beads jewelry buckls pens and many more decorative things.
Process.
Take a thermos and add one cup of milk and heat it after heating it add 3,4 spoon of vinagar and place it aside for sometime until you will see the milk turns to plastic like shape this was very useful method for making plastic.
