प्रश्न
Chlorine exists in two isotopic forms, \[\ce{Cl-37}\] and \[\ce{Cl-35}\] but its atomic mass is 35.5. This indicates the ratio of \[\ce{Cl-37}\] and \[\ce{Cl-35}\] is approximately
विकल्प
1:2
1:1
1:3
3:1
उत्तर
1:3
Explanation:
The chlorine is a mixture of two isotopes with atomic masses 37 U and 35 U and its atomic mass is 35.5 U. The atomic mass depicts that % composition of \[\ce{Cl-35}\] is much higher than that of \[\ce{Cl-37}\] and they are present in the ratio 1:3.
