Answer:
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
The answer is A

Answer:
31.31× 10²³ number of Cl⁻ are present in 2.6 moles of CaCl₂ .
Explanation:
Given data:
Number of moles of CaCl₂ = 2.6 mol
Number of Cl₂ ions = ?
Solution:
CaCl₂ → Ca²⁺ + 2Cl⁻
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
In one mole of CaCl₂ there are two moles of chloride ions present.
In 2.6 mol:
2.6×2 = 5.2 moles
1 mole Cl⁻ = 6.022 × 10²³ number of Cl⁻ ions
5.2 mol × 6.022 × 10²³ number of Cl⁻ / 1mol
31.31× 10²³ number of Cl⁻
Answer:
number. so the option is c
