What is the total number of moles in 80.0 grams of c2h5cl

(80.0g C2H5Cl) × (1 mol C2H5Cl/64.5g C2H5Cl)

= 1.24 mol C2H5Cl

Hope this helps!

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
