(a)
Interpretation:
The total number of moles of gas in the sample has to be calculated.
Concept Introduction:
Ideal gas equation is an equation that is describing the state of an imaginary ideal gas.
Where,
P is the pressure of the gas
V is the volume
n is the number of moles of gas
R is the universal gas constant
T is the temperature
Number of moles:
It is a physical property, which is defined as the mass of a given substance divided by the amount of substance. Unit of the mole is
(b)
Interpretation:
The pressure of the sample has to be calculated.
Concept Introduction:
Ideal gas equation is an equation that is describing the state of an imaginary ideal gas.
Where,
P is the pressure of the gas
V is the volume
n is the number of moles of gas
R is the universal gas constant
T is the temperature
(c)
Interpretation:
The partial pressure of the each component in the sample has to be calculated.
Concept Introduction:
Partial Pressure:
Dalton’s law of partial pressure states that “the total pressure (P) of the mixture is equal to the sum of the partial pressures
The
(d)
Interpretation:
The liberated heat in kilojoules sample has to be calculated.
Concept Introduction:
Heat liberation:
The amount of heat released in a course of reaction is known as liberation of heat.
When the reaction goes the molecules goes change in heat combustion at a certain pressure.
Heat liberated=
