Sagot :
Answer:
2.87 g
Explanation:
Step 1: Given data
- Temperature (T): 293 K
- Total pressure (P): 754.0 mmHg
- Partial pressure of water (pW): 17.55 mmHg
- Volume of gas (V): 1.62 L
Step 2: Calculate the partial pressure of CO₂
The total pressure is the sum of the partial pressures of CO₂and water.
P = pCO₂ + pW
pCO₂ = P - pW = 754.0 mmHg - 17.55 mmHg = 736.5 mmHg
We will convert this pressure to atm using the conversion factor 1 atm = 760 mmHg.
736.5 mmHg × 1 atm/760 mmHg = 0.9691 atm
Step 3: Calculate the moles (n) of CO₂
We will use the ideal gas equation.
P × V = n × R × T
n = P × V/R × T
n = 0.9691 atm × 1.62 L/(0.0821 atm.L/mol.K) × 293 K = 0.0653 mol
Step 4: Calculate the mass corresponding to 0.0653 moles of CO₂
The molar mass of CO₂ is 44.01 g/mol.
0.0653 mol × 44.01 g/mol = 2.87 g
The pressure exert on the one gas in the mixture by the other gases is called partial pressure.
The answer to the question is 2.87g.
The data is given in the question and the data is as follows:-
- Temperature (T): 293 K
- Total pressure (P): 754.0 mmHg
- Partial pressure of water (pW): 17.55 mmHg
- Volume of gas (V): 1.62 L
In the question we have to find the total pressure is the sum of the partial pressures of CO₂ and water. The equation we gonna use is:-
[tex]P = pCO_2 + pW[/tex]
To find the pCO2,
[tex]pCO_2= P - pW \\= 754.0 mmHg - 17.55 mmHg \\= 736.5 mmHg[/tex]
Pressure must be in ATM therefore, 1 atm = 760 mmHg.
=[tex]\frac{736.5 mmHg * 1 atm}{760 mmHg} = 0.9691 atm[/tex]
The ideal gas equation is as follows:-
[tex]PV = nRT\\n =\frac{PV}{RT}\\n = \frac{ 0.9691 atm * 1.62 L}{(0.0821 atm.L/mol.K) × 293 K}\\ = 0.0653 mol[/tex]
The mass of the following is:-
The molar mass of CO₂ is 44.01 g/mol.
Therefore,
[tex]0.0653 mol * 44.01 g/mol \\= 2.87 g[/tex]
Hence, the correct answer is 2.87g.
