Explanation:
<h3>Answer:</h3>
232.9 m³
<h3>Solution:</h3>
According to <em>Boyle's Law</em>, " The Volume of a given mass of gas at constant temperature is inversely proportinal to the applied Pressure". Mathmatically the initial and final states of gas are given as,
P₁ V₁ = P₂ V₂ ----------- (1)
Data Given;
P₁ = 1.1 atm
V₁ = 180 m³
P₂ = 0.85 atm
V₂ = ?
Solving equation 1 for V₂,
V₂ = P₁ V₁ / P₂
Putting values,
V₂ = (1.1 atm × 180 m³) ÷ 0.85 atm
V₂ = 232.9 m³
<h3>Result:</h3>
As the pressure has decreased from 1.1 atm to 0.85 atm, therefore, volume got increased from 180 m³ to 232.9 m³.

Answer:</h3>
0.073 M
<h3>
Explanation:</h3>
We are given;
Initial concentration, M1 of NaOH solution as 0.660 M
Initial volume,V1 of solution as 50.0 mL
Final volume,V2 of solution after dilution as 450 mL
We are required to calculate the final concentration, M2.
We are going to use the concept on dilution.
- Dilution involves addition of solvent to a concentrated solution to make it dilute.
- This results to an increase in the final volume of solution and a decrease in the concentration of the solution.
Using dilution formula,
M1V1 = M2V2
M2 = M1V1 ÷ V2
= (0.660 M × 50.0 mL) ÷ 450.0 mL
= 0.0733 M
= 0.073 M
Thus, the final concentration of the solution is 0.073 M
