Answer 2

Answer:

So to solve this question we make use of simple formula ime A=A°/2^n

where A is amount left atfer decomposition

A° is the initial concentration (160mg)

and n is numer of half lives

Ist step is calculation of n

n= 24/6 = 4

as mentioned atfer 1 day i.e 24 hours

now ue formula

A=A°/2°4

A= 160/16 (2 raise to 4 is 16 )

A=10 answer
