10 g platinum is equal to 0,05 moles.
0.00512615466634
The answer is 1,594 mol.
2,89 moles of aluminium contain 17,40398707673.1023 atoms.
The standard atomic weight of platinum is 195,084 g.195,084 g-------------------------------1 mol250 g-------------------------------------x molx = 250/195,084 = 1,28 mol platinum
This depends on: the volume of the cube, the density of the metal, the atomic weight of the metal.

2,2 moles of plutonium: 13,248711938.1023 atoms.
This depends on: the volume of the cube, the density of the metal, the atomic weight of the metal.
That would be 2 moles of OH- (hydroxide) ions because there are 2 of them associated with each 1 of the group II metal.
Approx. 0,5 moles.
The answer is 1.35 moles.425 g of UF4 would be 1.35 moles.
