Determining the mass of a compound or any substance from its number of moles, you would need data on its molar mass since it allows the conversion from moles to grams and grams to moles. For aluminum, it has an atomic mass of 26.98 g/mol.

3.57 mol Al ( 26.98 g / mol ) = 96.32 g Al

Molar mass is defined as the mass of the substance given in grams divided by the number of moles of that substance. Molar mass is denoted in g/mol.

The given mass of the Aluminum is 96.32 grams.

Given:

  • Moles of Aluminum = 3.57 mol
  • Molecular mass of Al = 26.91 g
  • Given Mass of Aluminum = ?

Applying the formula of mass, we have:

[tex]\rm mass &= \dfrac{given\; mass}{number\; of \;moles}[/tex]

[tex]\begin {aligned} \rm 26. 91 g &= \rm \dfrac{given\; mass}{3.57 mol}\\\\\rm 26.91 \times 3.57 &= \rm given\; mass \end[/tex]

Given mass = 96.32 g Aluminum

Thus, the given mass of the Aluminum is 96.32 grams.
