The number of moles of gas in the container would be 4.62 moles
<h3>Ideal gas law</h3>
According to the ideal gas law:
PV = nRT, where P = pressure, V, volume, n = mole number, and R = constant = 8.31
In this case, V = 58.953 L, P 467.81 kPa, and T = 719.11 K
Making n the subject:
n = PV/RT = 58.953 x 467.81/8.31 x 719.11 = 4.62 moles

Answer: The entropy change of the surroundings will be -17.7 J/K mol.
Explanation: The enthalpy of vapourization for 1 mole of acetone is 31.3 kJ/mol
Amount of Acetone given = 10.8 g
Number of moles is calculated by using the formula:
Molar mass of acetone = 58 g/mol
Number of moles =
If 1 mole of acetone has 32.3 kJ/mol of enthalpy, then
0.1862 moles will have =
To calculate the entropy change for the system, we use the formula:
Temperature = 56.2°C = (273 + 56.2)K = 329.2K
Putting values in above equation, we get
(Conversion Factor: 1 kJ = 1000J)
At Boiling point, the liquid phase and gaseous phase of acetone are in equilibrium. Hence,
Answer: separate a heterogeneous mixture.
Explanation: when a solid is mixed with a liquid and remains in souls chucks, then the mixture is heterogeneous. This is the case with coffee grounds in a cup of coffee.
Oxygen has an oxidation state of -2 so considering that there are 2 oxygen atoms,
2 x -2 = -4
The compound is neutrally charged so the sum of all the oxidation states must be zero. Therefore the oxidation state of Ge must be +4 in order to cancel the -4 to make zero.
