To calculate the molar mass of a compound like NaNO4 (sodium perchlorate), you need to sum up the atomic masses of all the atoms present in the compound.
The atomic masses of the elements are as follows:
- Sodium (Na) - Atomic mass: 22.99 g/mol
- Nitrogen (N) - Atomic mass: 14.01 g/mol
- Oxygen (O) - Atomic mass: 16.00 g/mol
Now, let's calculate the molar mass of NaNO4:
Molar mass of NaNO4 = (Atomic mass of Na) + (Atomic mass of N) + 4 * (Atomic mass of O)
Molar mass of NaNO4 = (22.99 g/mol) + (14.01 g/mol) + 4 * (16.00 g/mol)
Molar mass of NaNO4 = 22.99 g/mol + 14.01 g/mol + 64.00 g/mol
Molar mass of NaNO4 = 101.00 g/mol
Therefore, the molar mass of NaNO4 (sodium perchlorate) is approximately 101.00 g/mol.
