Answer: where a lever rests or is supported and where it pivots
Explanation:
Answer:
1.08 g/L is the density of air.
Explanation:
Pressure of the gas = P (atm)
Volume of the gas = V (L)
Moles of gas = n = 
Temperature of the gas = T (K)



where:
D = density of the gas = 
R = universal gas constant
w = Mass of the gas
M =Molar mass of the gas
Given = P = 1.0 atm , T = 54°C = 327.15 K
Average molar mass of the gas = 29 g/mol
Putting all the given values in above equation.


D = 1.08 g/L
1.08 g/L is the density of air.
Solid to Gas is Sublimation. Gas to Solid is Deposition.
