The relation between the volume and the temperature of the gas is given by Charles's law. The final temperature of the gas at 0.75 liters is -193.8°C.
<h3>What is Charles's law?</h3>
Charles's law was derived from the ideal gas equation and is used to state the relationship between the temperature and the volume of the gas. With a decrease in volume the temperature decreases.
If the pressure is kept constant then with an increase in temperature the volume of the gas expands. The law is given as,
V₁ ÷ T₁ = V₂ ÷ T₂
Given,
Initial volume (V₁) = 2.80 L
Initial temperature (T₁) = 23 °C = 296.15 K
Final volume (V₂) = 0.75 L
Final temperature = T₂
Substituting the values above as:
T₂ = (V₂ × T₁) ÷ V₁
= 0.75 × 296.15 ÷ 2.80
= 79.325 K
Kelvin is converted as, 79.325K − 273.15 = -193.8°C
Therefore, the final temperature is -193.8°C.

Answer:
Percent yield = 91%
Explanation:
Given data:
Percent yield of TiO₂ = ?
Actual yield = 10.2 g
Mass of TiCl₄ react = 25.7 g
Solution:
Chemical equation:
TiCl₄ + O₂ → TiO₂ + 2Cl₂
Number of moles of TiCl₄:
Number of moles = mass/molar mass
Number of moles = 25.7 g/ 189.7 g/mol
Number of moles = 0.14 mol
Now we will compare the moles of TiCl₄ and TiO₂.
TiCl₄ : TiO₂
1 : 1
0.14 : 0.14
Theoretical yield:
Mass = number of moles ×molar mass
Mass = 0.14 mol × 79.86 g/mol
Mass = 11.2 g
Percent yield:
Percent yield = [actual yield / theoretical yield ] × 100
Percent yield = [10.2 g / 11.2 g ]× 100
Percent yield = 91%
