Question

You have a 8 mol pure sample of an unknown material. After 2.7 h, you discover that 91% has decayed. Determine the half-life, decay constant, mean life, & initial decay rate. Also determine what the decay rate is at 2.7 h.
T_1/2 =  
λ =   h^-1
τ =
R_o = decays/h
R = decays/h

Please show the formulas used and explain them. Thanks
