Answer:
C . 24 L
Explanation:
Given data:
Initial volume of gas = 20.0 L
Initial pressure of gas = 660 mmHg
Final volume = ?
Final pressure = 550 mmHg
Solution:
The given problem will be solved through the Boly's law,
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
Now we will put the values in formula,
P₁V₁ = P₂V₂
660 mmHg × 20.0 L = 550 mmHg × V₂
V₂ = 13200 mmHg. L/ 550 mmHg
V₂ = 24 L
Answer: 1
Explanation:
The number of times a machine increases a force exerted on it The input force will be the same as the output force.
LaChatelier's Principle
LaChatelier's Principle is a principle stating that if a constraint (such as a change in pressure, temperature, or concentration of a reactant) is applied to a system in equilibrium, the equilibrium will shift so as to tend to counteract the effect of the constraint.
Answer:0.477 g/ml
Explanation:
Density=(40.14-33.79)/13.3 ml
Density=6.35/13.3
Density=0.477 g/ml
