Question

Sabiendo que cloro tiene dos isotopos naturales cuya abundancia es:
35 17 Cl = 75,40% y 37 17 Cl = 24,60%
calcula su masa atomica promedio

​

Answer 1

Respuesta:

35 17 Cl = 75,40% y 37 17 Cl = 24,60%

Explicación:

75.40/100=0.754

24.60/100=0.246

(35.17*0.754+37.17*0.246)/0.754+0.246

=35.7 uma
