To determine the molar mass of H2UO4, we need to calculate the sum of the atomic masses of all the atoms in the molecule. Let's break it down:
H2UO4 consists of:
- 2 hydrogen atoms (H)
- 1 uranium atom (U)
- 4 oxygen atoms (O)
The atomic masses of these elements are approximately:
- Hydrogen (H): 1.00784 g/mol
- Uranium (U): 238.02891 g/mol
- Oxygen (O): 15.999 g/mol
Now we can calculate the molar mass:
(2 * 1.00784 g/mol) + (1 * 238.02891 g/mol) + (4 * 15.999 g/mol)
= 2.01568 g/mol + 238.02891 g/mol + 63.996 g/mol
= 304.04059 g/mol
Therefore, the molar mass of H2UO4 is approximately 304.04059 g/mol.
