u may b asked to find the *number* of moles ..... so we hv to ultiply with this avagadro
constant (6.02*10^23)
as, by definition : mole is the amount containing a no. of particles equal to avagadro constant

Q7c) N/No = 1/10
N/No = e^(-decayconstant * t)
putting the values nd solve for t = 3.11*10^4 sec convert into hrs dividing by 3600 = 8.63 hrs.

Hello,
I didn't understand how you solved this part of the question. How did you get N/No = 1/10?
I'll be really grateful if you could explain the whole solution in detail.
Jazakallah
