Answer:
The right answer is "60.56 atm".
Explanation:
As we know,
Vander wall's equation is:
⇒ 
or,
⇒ 
Here,
a = 3.59 L² atm mol⁻²
b = 0.0427 L mol⁻¹
By putting the values in the above equation, we get
⇒ 



Answer:
Option B. 1 calcium, 2 oxygen, and 2 hydrogen
Explanation:
The number of each atoms present in Ca(OH)2 can be summarised as follow:
Calcium (Ca) = 1
Oxygen (O) = 2
Hydrogen (H) = 2
From the above illustration, we can see clearly that Ca(OH)2 contains 1 calcium, 2 oxygen and 2 hydrogen.
