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:

22.05 mol\times 114.22 g/mol=2,518.55 g

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

Charra [1.4K]

Answer:

An acid is a substance that donates protons (in the Brønsted-Lowry definition) or accepts a pair of valence electrons to form a bond (in the Lewis definition). A base is a substance that can accept protons or donate a pair of valence electrons to form a bond. Bases can be thought of as the chemical opposite of acids.
