Answer:
22.74%
Explanation:
The mass of nitrogen is 55g
The mass of Fe(NO3)3 is 241.86g/mol
%of nitrogen= mass of nitrogen/molar mass of Fe(NO3)3 ×100
= 55/241.86×100
=5500/241.86
=22.74%
Answer:
35.45 amu is the average atomic mass of chlorine.
Explanation:
The average atomic mass is given :
Atomic mass of 35-Cl = 34.968 amu
Percentage abundance of 35-Cl = 75.53%
Fractional abundance of 35-Cl = 0.7553
Atomic mass of 37-Cl = 36.956 amu
Percentage abundance of 37-Cl = 24.47%
Fractional abundance of 37-Cl = 0.2447
Average atomic mass of chlorine:
35.45 amu is the average atomic mass of chlorine.
Answer:
XCH₄ = 0.461
XCO₂ = 0.539
Explanation:
Step 1: Given data
- Partial pressure of methane (pCH₄): 431 mmHg
- Partial pressure of carbon dioxide (pCO₂): 504 mmHg
Step 2: Calculate the total pressure in the container
We will sum both partial pressures.
P = pCH₄ + pCO₂
P = 431 mmHg + 504 mmHg = 935 mmHg
Step 3: Calculate the mole fraction of each gas
We will use the following expression.
Xi = pi / P
XCH₄ = pCH₄/P = 431 mmHg/935 mmHg = 0.461
XCO₂ = pCO₂/P = 504 mmHg/935 mmHg = 0.539
