Concept explainers
(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:

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=

- 5-111 Diving, particularly SCUBA (Self-Contained Underwater Breathing Apparatus) diving, subjects the body to increased pressure. Each 10. m (approximately 33 ft) of water exerts an additional pressure of 1 atm on the body. (a) What is the pressure on the body at a depth of 100. ft? (b) The partial pressure of nitrogen gas in air at 1 atm is 593 mm Hg. Assuming a SCUBA diver breathes compressed air, what is the partial pressure of nitrogen entering the lungs from a breathing tank at a depth of 100. ft? (c) The partial pressure of oxygen gas in the air at 2 atm is 158 mm Hg. What is the partial pressure of oxygen in the air in the lungs at a depth of 100. ft? (d) Why is it absolutely essential to exhale vigorously in a rapid ascent from a depth of 100. ft?arrow_forward5-107 If 60.0 g of NH3 occupies 35.1 L under a pressure of 77.2 in. Hg, what is the temperature of the gas, in °C?arrow_forwardYou have a gas, one of the three known phosphorus-fluorine compounds (PF3, PF3, and P2F4). To find out which, you have decided to measure its molar mass. (a) First, yon determine that the density of the gas is 5.60 g/L at a pressure of 0.971 atm and a temperature of 18.2 C. Calculate the molar mass and identify the compound. (b) To check the results from part (a), you decide to measure the molar mass based on the relative rales of effusion of the unknown gas and CO2. You find that CO2 effuses at a rate of 0.050 mol/min, whereas the unknown phosphorus fluoride effuses at a rate of 0.028 mol/min. Calculate the molar mass of the unknown gas based on these results.arrow_forward
