Given :
Mass of granite , m = 20 g .
Change in temperature , .
Specific heat capacity of granite , .
To Find :
The heat absorbed by granite .
Solution :
We know , heat absorb is given by :
Therefore , heat absorb is 300.2 J .
Hence , this is the required solution .
Answer:
Explanation:
According to the Dalton's law of partial pressure, the total pressure of the gaseous mixture is equal to the sum of the pressure of the individual gases.
Partial pressure of carbon dioxide = 401 mmHg
Partial pressure of hydrogen gas = 224 mmHg
Total pressure,P = sum of the partial pressure of the gases = 401 + 224 mmHg = 625 mmHg
Also, the partial pressure of the gas is equal to the product of the mole fraction and total pressure.
So,
Similarly,
