What is difference between vapor pressure and vapor density?
Vapor pressure is the pressure exerted by a vapor in equilibrium with its condensed phase (liquid or solid) at a given temperature. Vapor density, on the other hand, is the mass of a vapor per unit volume of air. In essence, vapor pressure relates to the equilibrium between the vapor and its condensed phase, while vapor density pertains to the mass of vapor in a given volume of air.
A 4.0 liter sample of gasoline weighs 2700 grams What is the density of the gasoline expressed in the units gram per ml?
Density is calculated by dividing the mass of the substance by its volume. In this case, the density of gasoline would be 2700 grams ÷ 4000 ml = 0.675 grams/ml. So, the density of the gasoline is 0.675 grams per milliliter.
What are the reactants and products of the burning of gasoline?
The reactants of burning gasoline are gasoline (hydrocarbon fuel) and oxygen. The products of burning gasoline are carbon dioxide, water vapor, and heat energy.
What temperature can gasoline still give off flammable vapor?
The FR (flammable range) of gasoline is 1.4% LEL (lower exposive limit) to 7.6 UEL (upper exposive limit). Below 1.4% the gasoline vapor is said to be too lean and above 7.6% and the vapor is too rich. In either case gasoline will not burn if it is not in the FR.
Is gasoline lighter than motor oil?
Yes, gasoline is generally lighter than motor oil. Gasoline has a lower density, typically around 0.71 to 0.77 grams per milliliter, while motor oil usually has a density ranging from about 0.85 to 0.9 grams per milliliter. This difference in density means that gasoline will float on top of motor oil if the two are mixed.
Is gasoline a liquid or a vapor form?
Gasoline is a liquid, gas is a vapor.
What is the Reid vapour pressure of gasoline?
Reid vapor pressure (RVP) of gasoline is the vapor pressure at 100°F.
What is the density of gasoline?
The density of gasoline can vary depending on the type and temperature, but it is typically around 0.74-0.85 grams per cubic centimeter.
How do you calculate weight of gasoline in tank?
To calculate the weight of gasoline in a tank, you would need to know the volume of gasoline in the tank and its density. Multiply the volume by the density to get the weight. The density of gasoline can vary depending on factors such as temperature and composition.
Will a gas with a vapor density of 1.2 float or sink in air?
A gas with a vapor density less than 1 will float in air, while a gas with a vapor density greater than 1 will sink. Since the vapor density of the gas is 1.2, it will sink in air.
What has a greater density water or gasoline?
Water has a higher density than gasoline. The density of water at room temperature is approximately 1 g/cm3, whereas gasoline has a lower density, typically around 0.7 g/cm3.
What is difference between vapor pressure and vapor density?
Vapor pressure is the pressure exerted by a vapor in equilibrium with its condensed phase (liquid or solid) at a given temperature. Vapor density, on the other hand, is the mass of a vapor per unit volume of air. In essence, vapor pressure relates to the equilibrium between the vapor and its condensed phase, while vapor density pertains to the mass of vapor in a given volume of air.
How much does a gallon of gasoline vapor weigh?
Briefly, the saturated vapor volume of an average gallon of liquid gasoline when fully evaporated is 160.4 gallons of vapor at 60° F and sea level.Vapor volume of a liquid is the number of cubic feet of vapor resulting from the complete evaporation of the liquid. The vapor volume depends on parameters of density, temperature, pressure and molecular weight which is affected by the variety of formulas for gasoline that is comprised of a wide range of hydrocarbons.Several approaches are available to solve this problem. One is shown below.Using a common industrial formula:one liquid gallon = [(8.31) x (SG) x (387 cu ft)] / (MW)Where:8.31 = pounds in gallon of waterSG = specific gravity of liquid being vaporized387 = At standard conditions, one pound-molecular weight of a material will evaporate to fill 387 cubic feet of space.MW= molecular weight of liquid being vaporizedThen using the approximate gasoline constants:one liquid gallon of gasoline = [(8.31 pounds in a gallon of water) x (.70 approx. specific gravity of gasoline) x (387 cu ft)] / (105 molecular weight of average gasoline)= 21.4 cubic feet of vapor volumeThere is 7.481 U.S. gallons in one cubic foot.So:one liquid gallon of gasoline = (21.4 cubic feet) x (7.481)= 160.4 gallons of saturated gasoline vaporThe vapor volume will vary based on the specific formulation of gasoline, pressure, and temperature.D.

What is the vapor density of carbon mono oxide?
The vapor density of carbon monoxide is 14.0 g/L at standard temperature and pressure (STP). This means that carbon monoxide is slightly lighter than air, which has a vapor density of 28.97 g/L at STP.
What gasoline has a density of 15 degrees?
Gasoline typically has a density of around 0.72-0.74 g/mL at 15 degrees Celsius.
What characteristics of gasoline makes it such a dangerous liquid?
Gasoline vapor reacts explosively with the oxygen in air if ignited.
What does the Reid vapor pressure test measure?
The volatility of gasoline.
