Answer:
The answer to your question is P = 1.357 atm
Explanation:
Data
Volume = 22.4 L
1 mol
temperature = 100°C
a = 0.211 L² atm
b = 0.0171 L/mol
R = 0.082 atmL/mol°K
Convert temperature to °K
Temperature = 100 + 273
= 373°K
Formula
Substitution
Simplify
(P + 0.0094)(22.3829) = 30.586
Solve for P
P + 0.0094 =
P + 0.0094 = 1.366
P = 1.336 - 0.0094
P = 1.357 atm

First, you need to find:
One mole of
is equivalent to how many grams?
Well, for this you have to look up the periodic table. According to the periodic table:
The atomic mass of Calcium Ca = 40.078 g (See in group 2)
The atomic mass of <span>Chlorine Cl = 35.45 g (See in group 17)
</span>
As there are two atoms of Chlorine present in, therefore, the atomic mass of would be:
Atomic mass of = Atomic mass of Ca + 2 * Atomic mass of Cl
Atomic mass of = 40.078 + 2 * 35.45 = 110.978 g
Now,
110.978 g of = 1 mole.
75.9 g of = 
= 0.6839 moles.
Hence,
The total number of moles in 75.9g of = 0.6839 moles
According to <span>Avogadro's number,
1 mole = 1 * </span>
molecules
0.6839 moles = 0.6839 * molecules = 
molecules
Ans: Number of molecules in 75.9g of = molecules
