To calculate the molar mass of Al2(SO4)3 (aluminum sulfate), we need to determine the atomic masses of each element and multiply them by their respective subscripts.
The atomic mass of aluminum (Al) is approximately 26.98 grams/mol.
The atomic mass of sulfur (S) is approximately 32.06 grams/mol.
The atomic mass of oxygen (O) is approximately 16.00 grams/mol.
Now let’s calculate the molar mass of aluminum sulfate:
2(Al) + 3(S) + 12(O)
= 2(26.98) + 3(32.06) + 12(16.00)
= 53.96 + 96.18 + 192.00
= 342.14 grams/mol
Therefore, the molar mass of Al2(SO4)3 (aluminum sulfate) is approximately 342.14 grams/mol.
