Answer:
Partial pressure of Ne = 366 mmHg
Explanation:
In a mixture, the sum of partial pressures for each gas, is the total pressure for the system.
Partial pressure He: 43 mmHg
Partial pressure Ar: 835 mmHg
Partial pressure Xe: 111 mmHg
Partial pressure Ne: ?
Total pressure = 1355 mmHg
43 + 835 + 111 + x = 1355
989 + x = 1355
x = 1355 - 989 → 366
Answer:
V₂ = 4.82 L
Explanation:
Given data:
Initial volume of gas = 3.5 L
Initial pressure = 115 Kpa
Final volume = ?
Final Pressure = 625 torr
Solution:
Final Pressure = 625 torr (625/760 =0.82 atm)
Initial pressure = 115 Kpa (115/101 = 1.13 atm)
The given problem will be solved through the Boly's law,
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
Now we will put the values in formula,
P₁V₁ = P₂V₂
1.13 atm × 3.5 L = 0.82 atm × V₂
V₂ = 3.955 atm. L/0.82 atm
V₂ = 4.82 L
The calculated atomic mass of silicon is 28.104 u.
The average atomic mass of Si is the <em>weighted average</em> of the atomic masses of its isotopes.
We multiply the atomic mass of each isotope by a number representing its <em>relative importance</em> (i.e., its % abundance).
Thus,
0.922 97 × 27.9769 u = 25.821 8 u
0.046 832 × 28.9765 u = 1.357 03 u
0.030 872 × 29.9738 u = <u>0.925 351 u
</u>
TOTAL = 28.104 u
Note: Your percentages don’t add up to 100.0000 % (I think the first one is incorrect).
