Answer:
The atomic masses are as follows:
- Na (sodium): 22.99 g/mol
- H (hydrogen): 1.01 g/mol
- S (sulfur): 32.07 g/mol
- O (oxygen): 16.00 g/mol
To calculate the formula weight, add the atomic masses of each element in the compound:
NaHSO4: (1 * Na) + (1 * H) + (1 * S) + (4 * O)
= (1 * 22.99 g/mol) + (1 * 1.01 g/mol) + (1 * 32.07 g/mol) + (4 * 16.00 g/mol)
= 22.99 g/mol + 1.01 g/mol + 32.07 g/mol + 64.00 g/mol
= 120.07 g/mol
Therefore, the formula weight of NaHSO4 is 120.07 g/mol.
