Answer 2

Mr-Al2(SO4)3 represents the molar mass of the compound aluminum sulfate, which is denoted by the chemical formula Al2(SO4)3. To calculate the molar mass, we need to consider the atomic masses of the individual elements present in the compound.

The atomic masses of the elements are as follows:

• Aluminum (Al) = 26.98 g/mol
• Sulfur (S) = 32.06 g/mol
• Oxygen (O) = 16.00 g/mol

Now, let's calculate the molar mass of aluminum sulfate:

Molar mass of Al2(SO4)3 = (2 * Al) + (3 * (S + (4 * O))) = (2 * 26.98) + (3 * (32.06 + (4 * 16.00))) = 53.96 + (3 * (32.06 + 64.00)) = 53.96 + (3 * 96.06) = 53.96 + 288.18 = 342.14 g/mol

Therefore, the molar mass of aluminum sulfate (Al2(SO4)3) is approximately 342.14 g/mol.
