Question

what is the molar mass of aluminum carbonate al₂(co₃)₃? 234.0 g/mole 114.0 g/mole 87.99 g/mole 186.0 g/mole

Explanation:

Step1: Determine the molar mass of each element

The molar mass of Al is \(26.98\ g/mol\), of C is \(12.01\ g/mol\), and of O is \(16.00\ g/mol\).

Step2: Calculate the molar mass of \(Al_2(CO_3)_3\)

• For Al: \(2\times26.98 = 53.96\ g/mol\)
• For C: \(3\times12.01=36.03\ g/mol\)
• For O: \(9\times16.00 = 144.0\ g/mol\)
• Total molar mass: \(53.96+36.03 + 144.0=233.99\approx234.0\ g/mol\)

Answer:

234.0 g/mole
