# What is the molar mass of al2(so4)3 [Solved] 342.17 g/mol Explanation: Molecular formulas is the actual number of atoms of each element in the compound. Molecular mass is the sum of the mass of each element which is present in the molecular formula is multiplied by their subscript which appear in the molecular formula.
Given, The formula is = Mass from the formula = 2Molar mass of Aluminium 3Molar mass of sulfur 12Molar mass of Oxygen Molar mass of Aluminium = 27.00 g/mol Molar mass of sulfur = 32.06 g/mol Molar mass of Oxygen = 15.99 g/mol So, Mass from the formula = 227.00 332.06 1215.99 g/mol 342.17 g/mol

1) we find out the atomic mass of these elements (Al, S, O)Atomic mass (Al)=27 amuAtomic mass (S)=32 amuAtomic mass (O)=16 amu2)Now, we calculate the molar mass of Al(SO)molar mass=2(27) 3[32 4(16)]=54 3(32 64)=54 3(96)=54 288=342 g/mol. 342.17 g/mol.
