The correct answer is [B] 108 grams

• To calculate the mass of 4 moles of aluminum atoms, we need to use the molar mass of aluminum, which is 26.98 g/mol.
• The molar mass is the mass of one mole of a substance, and it can be calculated by multiplying the atomic mass of the element by Avogadro’s number (6.022 x 10^23 atoms/mol).

Additional Information

A) 120 grams is not the correct answer because it is greater than the calculated mass of 107.92 grams.

B) 108 grams is the correct answer because if we multiply 4 moles (4 x 26.98), we get a total of 107.92 grams.

C) 136 grams is not the correct answer because it is greater than the calculated mass of 107.92 grams.

D) 140 grams is not the correct answer because it is greater than the calculated mass of 107.92 grams.

The correct answer is [B] 108 grams
