0.025 M will be the resulting concentration
Explanation:
To find the resulting concentration we use the following formula:
initial concentration × initial volume = final concentration × final volume
initial concentration = 0.15 M
initial volume = 2 mL
final concentration = ?
final volume = 10 + 2 = 12 mL
0.15 × 2 = final concentration × 12
final concentration = (0.15 × 2) / 12
final concentration = 0.025 M

Answer:
Final temperature = 149 K
Explanation:
Given data:
Initial temperature = 25°C (25+273 = 298 K)
Initial volume = 4.5 L
Final temperature = ?
Final volume = 9.0 L
Solution:
The given problem will be solve through the Charles Law.
According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.
Mathematical expression:
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
V₁/T₁ = V₂/T₂
T₂ = T₁V₂/V₁
T₂ = 4.5 L × 298 K / 9.0 L
T₂ = 1341 L K / 9.0L
T₂ = 149 K
