A 3.88 mol sample of gas has a temperature of 28°C and a pressure of 885 torr. What is its volume?
2 answers:
Answer:
Its volume is 82.3 L
Explanation:
The state of a quantity of gaseous matter is formulated based on four different variables: pressure, volume, temperature and number of moles of gas. Then, the equation known as the ideal gas equation, explains the relationship between these four variables using the expression:
P*V=n*R*T
where P represents the gas pressure, V its volume, n the number of moles of gas, R the gas constant and T the gas temperature.
In this case:
- P= 885 torr
- V=?
- n=3.88 mol
- R= 62.36365
- T=28°C= 301°K (Being 0°C=273°K)
Replacing:
885 torr*V=3.88 mol*62.36365 *301°K
Solving:
V=82.3 L
<u><em>Its volume is 82.3 L</em></u>

Answer:
The four quantum number for each electron will be:
Explanation:
As the element is neutral, the number of protons will be equal to number of electrons which will be the atomic number of the element.
Number of electrons =12
Atomic number = 12
Element : Magnesium
The principal shell is represented by "n"
i) For "s" subshell the value of l =0 (azimuthal quantum number) thus m (magnetic quantum number)= 0
The two electrons in s subshell will have either plus half or minus half spin quantum number
ii) for "p" subshell the value for l =1
thus m = 0 or +1 or -1
The two electrons in each orbital will have either plus half or minus half spin quantum number
Depression in freezing point (Δ
) = 
×m×i,
where, = cryoscopic constant = 
,
m= molality of solution = 0.0085 m
i = van't Hoff factor = 2 (For
)
Thus, (Δ) = 1.86 X 0.0085 X 2 = 
Now, (Δ) = 
- T
Here, T = freezing point of solution
= freezing point of solvent = 
Thus, T = - (Δ) = -
where,
m= molality of solution = 0.0085 m
i = van't Hoff factor = 2 (For
Thus, (Δ
Now, (Δ
Here, T = freezing point of solution
Thus, T =
