We have air (21% O2 and 79% N2) at 23 bar and 30 C. 4. What is the ideal molar volume (m^3/kmol)? a. b. What is the Z factor? What is the real molar volume?

The  ideal molar volume is    

The  Z factor is  

The  real molar volume is

Explanation:

From the question we are told that

    The pressure is  

      The temperature is  

According to the ideal gas equation we have that

=>      

Where   is the molar volume  and  R is the gas constant with value

substituting values

The  compressibility factor of the gas is mathematically represented  as

substituting values        

Now the real molar volume is evaluated as

substituting values

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.
