Uranium has an atomic weight of 238 amu. Meight of one mole of uranium= /g/mol Weight of one mole of oxygen=16.00g The molar mass or molecular weight for U_(2)O_(5) is div g/mol A

To calculate the molar mass of \( U_2O_5 \), we need to consider the atomic weights of uranium (U) and oxygen (O).<br /><br />1. **Atomic weight of Uranium (U):** 238 amu<br />2. **Atomic weight of Oxygen (O):** 16.00 amu<br /><br />The formula for \( U_2O_5 \) indicates that there are 2 uranium atoms and 5 oxygen atoms in one molecule.<br /><br />Now, let's calculate the molar mass:<br /><br />- Molar mass of \( 2 \) uranium atoms: \( 2 \times 238 = 476 \) g/mol<br />- Molar mass of \( 5 \) oxygen atoms: \( 5 \times 16.00 = 80.00 \) g/mol<br /><br />Adding these together gives the molar mass of \( U_2O_5 \):<br /><br />\[ 476 + 80.00 = 556.00 \text{ g/mol} \]<br /><br />Therefore, the molar mass of \( U_2O_5 \) is \( 556.00 \) g/mol.
