Question

. 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.​

Answer 1

The molar mass of aluminum trifluoride (AlF3) is calculated by summing the molar mass of one mole of aluminum (26.98 g/mol) with the molar mass of three moles of fluorine (19.00 g/mol each) to get a total of 83.98 g/mol.

Step-by-step explanation:

To calculate the molar mass of aluminum trifluoride, AlF3, we need to sum the molar masses of aluminum (Al) and fluorine (F) with the appropriate number of atoms in the compound. The molar mass of Al is given as 26.98 g/mol, and the molar mass of F is 19.00 g/mol. As there are three atoms of fluorine in aluminum trifluoride, we calculate the molar mass using the following equation:

Molar mass of AlF3 = (1 mol Al × 26.98 g/mol) + (3 mol F × 19.00 g/mol)

Molar mass of AlF3 = 26.98 g/mol + 57.00 g/mol

Molar mass of AlF3 = 83.98 g/mol

This calculated value represents the mass in grams for one mole of aluminum trifluoride.

Answer 2

83.98 g/mol

Step-by-step 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
