Required formula is N=N0*e^(-lamda*t)
?
360/4 = 90 considering it is half life then it would be 45
Here N0=360gram=initial amount of radioactive materials

ok
N=remaining amount of radioactive matetials after 32 hrs
U hv to find out N=?
e means exponential
im lost

Ok
U know an equation Lamda=0.693/half life
yea
Lamda=?
Half life is given

Half life=8 hrs
360/2=180/2=90/2=45/2=22.5
Just divide by 2 every 8 hours
