. The molar mass of aluminum is 26.98 g/mol and the molar mass of fluorine is 19.00 g/mol. Calculate the molar mass of aluminum trifluoride, AlF3.​

Sagot :

Answer:

83.98 g/mol

Explanation:

To find the molar mass of AlF₃, you need to add the individual molar masses of each element times their quantities. For instance, since there are 3 fluorine atoms in AlF₃, the molar mass of AlF₃ must include the molar mass of fluorine times 3.

Molar Mass (Al): 26.98 g/mol

Molar Mass (F): 19.00 g/mol

Molar Mass (AlF₃): 26.98 g/mol + 3(19.00 g/mol)

Molar Mass (AlF₃): 83.98 g/mol
