What is the formula weight of al(co3)3?

Answer 1

"In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in Atomic Mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together."

Regarding Aluminum, the atomic mass of Al is 26.981538 g/mol. Multiply that by 1 atom in Al and your molecular weight or molar mas is 26.981538 g/mol.

Answer 2

The formula weight of Al(CO3)3 (aluminum carbonate) is calculated by adding the atomic weights of all elements in the formula. The atomic weight of Aluminum (Al) is 26.98 g/mol, and the atomic weight of Carbon (C) and Oxygen (O) are 12.01 g/mol and 16.00 g/mol, respectively. Therefore, the formula weight of Al(CO3)3 would be (26.98 + 312.01 + 316.00) g/mol = 234.03 g/mol.

Answer 3

We can use the mass of alum to get the weight for alum. Density is mass divided by volume. By making use of this equation we can get the formula weight for alum.

Answer 4

The molar mass of aluminium carbonate - Al2(CO3)3 - is 233,99 g.
