Answer:
The gas will occupy a volume of 4000L
Explanation:
V1 = 2000L
T1 = 100K
P1 = 100kPa = 100*10³Pa
T2 = 400k
P2 = 200kPa = 200*10³kPa
V2 = ?
To solve this question, we need to use combined gas equation
[(P₁ * V₁) / T₁] = [(P₂ * V₂) / T₂]
V₂ = (P₁ * V₁ * T₂) / (P₂ * T₁)
V₂ = (100*10³ * 2000 * 400) / (200*10³ * 100)
V₂ = 8.0*10¹⁰ / 2.0*10⁷
V₂ = 4000L
The new volume of the gas is 4000L

<h3>
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
