Answer:
n O2 = 2.125 mol
Explanation:
balanced reaction:
- 2C6H10 + 17O2 → 12CO2 + 10H2O
∴ n CO2 = 1.5 mol
⇒ n O2 = (1.5 mol CO2)*(17 mol O2/12 mol CO2)
⇒ n O2 = 2.125 mol
The answer is 15g
The mass of a substance when given the density and volume can be found by using the formula
Mass = Density x Volume
From the question
Density of chloroform=1.5 g/ml
Volume=10mL
We have
Mass=1.5x10
We have the final answer as
15g
<u>Answer:</u> The new pressure will be 101.46 kPa.
<u>Explanation:</u>
To calculate the new pressure, we use the equation given by Gay-Lussac Law. This law states that pressure is directly proportional to the temperature of the gas at constant volume.
The equation given by this law is:

where,
are initial pressure and temperature.
are final pressure and temperature.
We are given:
By using conversion factor: 

Putting values in above equation, we get:

Hence, the new pressure will be 101.46 kPa.
