The half-life of a radioactive kind of iodine is 12 hours. how much will be left after 36 hours if you start with 832 grams of it

104 g

Step-by-step explanation:

Using half life formula

A= a(1/2)^t/h, where t represents the hours, h represents the half life of iodine, a is the original amount and A is how much is left

A=

=832(1/2)^3

=104 g left

21/58.

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26
