The sample would lose one half the quantity of francium in each half-life.
Thus a mass decrease by a factor of 16 would correspond to a period of four half-lives. It took 80 minutes for the sample to lose all these francium, therefore

Morality= wt\m.wt*1000\v(ml)
So the m.wt of h3po4 is 98.00g\ml
Molarity = 32.7g\98.00*1000\455ml
