6.02 x 10^23, basically a mole since the molar mass of carbon is 12
Answer:
2.95 * 10^23 atoms
Explanation:
The number of atoms in a mole is always equal to <u>Avogadro's constant</u>, which is <u>6.02214076×10²³ mol⁻¹</u>.
To find the number of atoms in 0.490 moles of barium, multiply it with <u>Avogadro's constant</u>:
0.490 mol * 6.02214076×10²³ mol⁻¹ ≈ 2.9508 * 10^23
Convert to SigFigs (if necessary):
2.95 * 10^23
The chemical formula of aluminum chloride is AlCl₃ and the chemical formula of aluminum oxide is Al₂O₃.
<h3>Aluminum chloride</h3>
The chemical formula of aluminum chloride is written as;
Al³⁺ + Cl⁻ → AlCl₃
<h3>Aluminum oxide</h3>
The chemical formula of aluminum oxide is written as;
Al³⁺ + O²⁻ → Al₂O₃
Thus, the chemical formula of aluminum chloride is AlCl₃ and the chemical formula of aluminum oxide is Al₂O₃.
