Concept explainers
Interpretation:
The partial pressure of hydrogen gas in the sample should be calculated and the mass of zinc in grams which is reacted to produce this quantity of hydrogen.
Concept Introduction:
Mole is SI unit which is used to measure the quantity of the substance. It is the quantity of a substance which contains same number of atoms as present in accurately 12.00 g of carbon-12 is known as mole.
Number of moles of a compound is defined as the ratio of given mass of the compound to the molar or molecular mass of the compound.
The mathematical expression is given by:
Number of moles =
Idea gas equation is:
Where,
P = pressure
V = volume
n = number of moles
R = universal gas constant
T = temperature
Dalton’s Law of partial pressure is used for calculating the total pressure of a mixture of gases.
It states that, in a mixture of two or more gases, the total pressure is equal to the sum of the partial pressures of individual gases.
The mathematical expression is:
The partial pressure of a gas is equal to the product of total pressure and mole fraction of a gas.
The mathematical expression is:
Where, P = pressure of a gas

Chemical Principles
- In the Mthode Champenoise, grape juice is fermented in a wine bottle to produce sparkling wine. The reaction is C6H12O6(aq)2C2H5OH(aq)+2CO2(g) Fermentation of 750. mL grape juice (density = 1.0 g/cm3) is allowed to take place in a bottle with a total volume of 825 mL until 12% by volume is ethanol (C2H5OH). Assuming that the CO2 is insoluble in H2O (actually, a wrong assumption), what would be the pressure of CO2 inside the wine bottle at 25C? (The density of ethanol is 0.79 g/cm3.)arrow_forwardHow many liters of HCI gas, measured at 30.0 C and 745 torr, are required to prepare 1.25 L of a 3.20-M solution of hydrochloric acid?arrow_forwardWhat possible uses exist for the natural gas liquids that are removed from natural gas during its processing?arrow_forward
- 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?
