<u>Answer:</u> The pressure that the gas exert at high temperature is 9.63 atm
<u>Explanation:</u>
To calculate the final pressure of the system, we use the equation given by Gay-Lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,
where,
are the initial pressure and temperature of the gas.
are the final pressure and temperature of the gas.
We are given:
Putting values in above equation, we get:
Hence, the pressure that the gas exert at high temperature is 9.63 atm
Answer:
1.8321 kg
Explanation:
The given 1 kg of coal contains 50% of the carbon atom by mass. Thus, mass of carbon in coal is
Also, 1 kg = 1000 g
So, mass of carbon = 500 g
The formula for the calculation of moles is shown below:
Molar mass of carbon = 12.0107 g/mol
Moles of methanol = 500 g / 12.0107 g/mol = 41.6295 moles
Considering the reaction:
From the reaction,
1 mole of C react to form 1 mole of
So,
41.6295 moles of C react to form 41.6295 moles of
Moles of = 41.6295 moles
Molar mass of = 44.01 g/mol
So, Mass = Moles × Molar mass = 41.6295 moles × 44.01 g/mol = 1832.1143 g
Also, 1g = 0.001 kg
<u>So, amount of released = 1.8321 kg</u>
