Where there is more uranium in 1.2 g of uranium chloride or 1.0 uranium oxide. Write down the formulas and justify the calculations.
Chemical formula of uranium (IV) chloride: U Cl4.
Chemical formula of uranium (IV) oxide: U О2.
The molar mass of uranium (IV) chloride is: M (U Cl4) = 238 + 35.5 × 4 = 380 g / mol.
The molar mass of uranium (IV) oxide: М (U О2) = 238 + 16 × 2 = 270 g / mol.
The mass of uranium in 1.2 g of uranium chloride: 1.2 × 238/380 = 0.752 g;
mass of uranium in 1.0 g of uranium oxide: 1.0 × 238/270 = 0.881 g.
Thus, there is more uranium in 1.0 g of uranium oxide than in 1.2 g of uranium chloride.
