Question

In chlorine gas ,ratio Cl 35 and Cl 37 is

Answer 1

Explanation:

Chlorine exists in two isotopic forms Cl-37 and Cl-35, but its atomic mass is 35.5. This indicates the ratio of Cl-37 and Cl-35 is approximately. (a) 1 : 2...

Answer 2

In chlorine gas, ratio of Cl 35 and Cl 37 is 3 : 1.

• Total mass of Cl is 35.5.
• Let x be fraction of Cl 37  and Cl 35 will be (1-x).  
• So, 37x + 35(1-x)= 35.5  
• 37x + 35 -35x = 35.5  
• 2x= 0.5  
• x = 0.25
• Hence, 25% Cl37.
• So, ratio is 3:1.
