Answer is: V has the units of liters, and T has the units of kelvin.
Ideal gas law: p·V = n·R·T.
atm · L = mol · L·atm/mol·K · K; both side of equatation have same values.
R = 0,08206 L·atm/mol·K; universal gas constant.
p is pressure of the gas, unit is standard atmosphere (atm).
V is volume of the gas, unit is liters (L).
n is amount of substance of the gas; unit is mole (mol).
T is temperature of the gas, unit is Kelvin (K).
Chemical energy is converted to thermal energy.

Answer:
5.5 × 10²² formula units Al₂O₃
General Formulas and Concepts:
<u>Chemistry - Stoichiometry</u>
- Reading a Periodic Table
- Dimensional Analysis
- Avogadro's Number - 6.022 × 10²³ atoms, molecules, formula units, etc.
Explanation:
<u>Step 1: Define</u>
9.3 g Al₂O₃
<u>Step 2: Define conversions</u>
Avogadro's Number
Molar Mass of Al - 26.98 g/mol
Molar Mass of O - 16.00 g/mol
Molar Mass of Al₂O₃ - 2(26.98) + 3(16.00) = 101.96 g/mol
<u>Step 3: Convert</u>
<u /> = 5.4928 × 10²² formula units Al₂O₃
<u>Step 4: Check</u>
<em>We are given 2 sig figs. Follow sig fig rules.</em>
5.4928 × 10²² formula units Al₂O₃ ≈ 5.5 × 10²² formula units Al₂O₃
