Today in the hospital , I took care of a woman from VEnezuela who's baby was just born yesterday.WHen I was explaining umbilical cord care to the mom (I do speak SPanish) I told her how the yellow pin clamping the umbilical cord would be removed before baby went home. She told me it is tradition to save the umbilical cord and the pin with it. She was very insistent that the pin be there also. Can anyone explain this tradition or know if they do it in other Latin American countries as well? Why does she want the pin on there, too?

Gracias!

Silicon has 3 isotopes, Si-28, Si-29, and Si-32.
If the mass (amu) of Si-28 is 27.98 with abundance of 92.21% and the mass of Si-32 is 29.97 3.09%, what is the mass of Si-29 with an abundance of 4.70%?
i dont know if abundance has anything to do with finding the mass, but just put it.
do i have to find the average mass (add the masses of Si-28 and 32 together and divide by 2?)
help please!!!! :) THANKS!
