The gram atomic mass of titanium is 47.867. Therefore, in a 0.65 mole sample, there will be 0.65 X 47.867) = 31 grams, to the justified number of significant digits.
There are 1.5 moles water in 27 grams

18 grams are one fourth of the original sample mass of 72 grams. Accordingly, the half life is 6.2/4 = 1.55 days.
The mass of o,5 mole of uranium is 119,014455 g.
