Uranium metal can be produced by the reaction of uranium tetrafluoride
(UF4) with magnesium (Mg) in a sealed reactor heated to 700oC. The by-product is
magnesium fluoride (MgF2). To ensure that all the magnesium is consumed in the
reaction, the reactor is charged with excess UF4, specifically 10% more than the
stoichiometric requirement of the reaction. To produce 222 kg of U, how much UF4
must be introduced into the reactor? Assume complete conversion of Mg. Express
your answer in kg.

All tutors here are American or Canadian. It is unlikely that a tutor who is qualified to help you with a question about nuclear physics will recognize characters in your language.
You want 222 Kg U so you will need 222 x (atomic mass U/molar mass UF4) = ? to start.
Then a 10% excess of that will be
? + 0.1*? = ??
Then a 10% excess of that will be
? + 0.1*? = ??
