To solve this problem it is fundamentally, just look for the volume of the gas and convert it to cm3. At STP 1 mole = 22.4 liters. 8.00 moles x 22.4 liters/mole = 179.2 liters = 179,200 cm^3 Then. get the cube root of 179,200 cm^3. This would be equal to 56.38 cm and thus would be the length of the edge of this cube.
Stereochemistry, a subdiscipline of chemistry, involves the study of the relative spatial arrangement of atoms that form the structure of molecules and their manipulation.
<h3>What is the use of stereochemistry?</h3>
Using stereochemistry, chemists can work out the relationships between different molecules that are made up from the same atoms. They can also study the effect on the physical or biological properties these relationships give molecules.
<h3>Why is it called stereochemistry?</h3>
The term “stereochemistry” is derived from the Greek “stereos” meaning solid—it refers to chemistry in three dimensions. Since nearly all organic molecules are three dimensional (with the exception of some olefins and aromatics to be discussed later), stereochemistry cannot be considered a branch of chemistry.

Answer:
FLASK B WHICH CONTAINS CO2 HAS THE HIGHEST NUMBER OF MOLECULES AS IT CONTAINS THE HIGHEST MOLECULAR MASS OF 44 G/MOL.
Explanation:
Flask A contains CH4
Flask B contaims CO2
Flask C contains N2
To know the flask containing the largest number of molecules, we find the molar mass of the molecules in the flask and the largest is the one with the highest number of the relative molecular mass.
Molecular Mass of CH4 (C = 12, H =1) = ( 12 + 1*4) g/mol
= 16 g/mol
Molecular mass of CO2 (C= 12, 0= 16) = (12 + 16*2) g/mol
= 12 + 32 g/mol
= 44 g/mol
Molecular mass of N2 (N=14) = 14 * 2 g/mol
= 28 g/mol
Hence, the flask with the largest number of molecules is the flask with the highest relative molecular mass. The highest molecular mass is 44 g/mol and it is for the gas CO2 in Flask B.
So therefore, Flask B has the highest number of molecules in it.
Answer:
3 : 1
Explanation:
The following data were obtained from the question:
Initial temperature (T₁) = T
Initial pressure (P₁) = P
Final temperature (T₂) = 3T
Final pressure (P₂) =..?
Since the volume is constant, we shall use the following formula P₁ /T₁ = P₂ /T₂ to obtain the final pressure. This is illustrated below:
P₁ /T₁ = P₂ /T₂
P/T = P₂ /3T
Cross multiply
T × P₂ = P × 3T
Divide both side by T
P₂ = P × 3T /T
P₂ = P × 3
P₂ = 3P
Therefore, the final pressure is tripled.
Finally, we shall determine the ratio of the final pressure to the initial pressure as follow:
Initial pressure (P₁) = P
Final pressure (P₂) = 3P
Final pressure (P₂) : Initial pressure (P₁)
P₂ : P₁ => 3P/P
P₂ : P₁ => 3 : 1
Therefore, the ratio of the final pressure to the initial pressure is 3 : 1
It would be +7 oxidation number.
(All compounds are zero)
Al is in group lll ( or 13 depending on the system) so the oxidation state is 3.
You have 12 O at -2 each for -24. That leaves you at -24+3= -21. So 3 Cl atoms must be +21 to balance the -21 there which makes +21/3 or +7 for each Cl.
