mass octane  = 2,518 g

Answer D

hope this helps!

Answer:

The mass of 22.05 mol of octane is 2,518 g.

Explanation:

Molar mass of octane = 114.22 g/mol

Mass of 1 mole of octane is 112.22 g/mol.

Mass of compound:

Moles of compound  × Molar mass of compound

Mass of 22.05 moles of octane is:

[tex]22.05 mol\times 114.22 g/mol=2,518.55 g[/tex]

The closest answer from the given options is 2,518 g.
