Answer:
3.09
Step-by-step explanation:
divide 2.2 by 6.8 then z would equal 3.09
Answer:
Enthalpy of Vaporization of substance X = 489.15KJ/mol
Step-by-step explanation:
The Concept of Clausius Clapeyron equation is applied. This equation allows us to calculate the vapor pressure of a liquid over a some range of temperatures. The Clausius Clapeyron equation make use of the assumption that the heat of vaporization does not change as the temperature changes.
The question has data attached to it, I have added the other details and a step by step derivation and application of the Clausius Clapeyron equation was done.

</span>Find Radius
------------------------------------
Radius = Diameter ÷ 2
Radius = 27 ÷ 2
Radius = 13.5 cm
------------------------------------
Find Area
------------------------------------
Area of circle x = πr²
Area of circle x = 3.14 x 13.5²
Area of circle x = 572.265 cm²
------------------------------------
Find Radius
------------------------------------
Radius = Diameter ÷ 2
Radius = 12 ÷ 2
Radius = 6 cm
------------------------------------
Find Area
------------------------------------
Area of circle y = πr²
Area of circle y = 3.14 x 6²
Area of circle y = 113.04 cm²
------------------------------------
Compare the area
------------------------------------
572.265 - 113.04 = 459.23 cm²
------------------------------------------------------------------------
Answer: Circle x is 459.23cm² greater than circle y.
