calculate the molar mass of al(c₂h₃o₂)₃. write your answer to 6 significant figures.
Answer
Explanation:
Step1: Identify atomic masses
The atomic mass of Al is 26.9815 g/mol, C is 12.0107 g/mol, H is 1.00794 g/mol, and O is 15.9994 g/mol.
Step2: Calculate mass from each element
In (Al(C_2H_3O_2)_3), there is 1 Al atom, 6 C atoms ((2\times3)), 9 H atoms ((3\times3)), and 6 O atoms ((2\times3)). The contribution of Al: (1\times26.9815 = 26.9815) g/mol. The contribution of C: (6\times12.0107=72.0642) g/mol. The contribution of H: (9\times1.00794 = 9.07146) g/mol. The contribution of O: (6\times15.9994=95.9964) g/mol.
Step3: Sum up the masses
(26.9815+72.0642 + 9.07146+95.9964=204.11356\approx204.114) g/mol.
Answer:
204.114 g/mol
