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
Any substance that contains only one type of atom is referred to as an element.Elements are the "building blocks" of everything. Each element only contains one type of atom. If substances carry more than one type of atom, then they are compounds.

Volume = Mass / Density
Volume = .842 / 2.70
Volume = .31185 cubic centimeters
Aluminum square * depth = .31185 cubic centimeters
6 * 6 * depth = .31185 cubic centimeters
depth = (.31185 cubic centimeters) / 36
