Which of the adhering to statements is correct concerning the gas phase? A gas expands spontaneously to fill its container. Depfinishing on their chemical nature, 2 or even more gases can form either a homogeneous or heterogeneous mixture. The volume of a gas is always much less than the volume of its container. When pressure is used to a gas, its volume boosts.

You are watching: What is the density (in g/l) of oxygen gas at 77.0 °c and 700.0 torr?


Air pressure is measured by a barometer. One type of barometer uses an evacuated, calibrated tube inverted in a pool of mercury that is open up to the environment. As air press increases, the mercury will climb in the column till the weight of the mercury in the column equates to the force exerted by the air on the surconfront of the pool. The barometer shown here (Figure 1) steps atmospheric push in millimeters of mercury (mmHg). According to this barometer, what is the atmospheric push P in inches of mercury (inHg)?
Air press is measured by a barometer. One form of barometer makes use of an evacuated, calibrated tube inverted in a pool of mercury that is open to the atmosphere. As air press increases, the mercury will certainly rise in the column till the weight of the mercury in the column equates to the force exerted by the air on the surface of the pool. At a press of 909 mbar, what would certainly the height of the mercury in the column of a mercury barometer?
What press in units of torr is equal to 1.14 atm of pressure? 116 torr 866 torr 1.16 torr 0.00150 torr
A certain amount of chlorine gas was placed inside a cylinder via a movable piston at one finish. The initial volume was 3.00 L and the initial push of chlorine was 1.35 atm. The piston was puburned down to readjust the volume to 1.00 L. Calculate the last push of the gas if the temperature and variety of moles of chlorine remajor consistent.
In an air-conditioned room at 19.0∘ C, a spherical balloon had actually the diameter of 50.0 cm. When taken exterior on a hot summer day, the balloon expanded to 51.0 cm in diameter. What was the temperature exterior in levels Celsius? Assume that the balloon is a perfect spbelow and also that the press and also variety of moles of air molecules remains the same.

A cylinder through a movable piston consists of 2.00 g of helium, He, at room temperature. More helium was included to the cylinder and also the volume was readjusted so that the gas pressure remained the exact same. How many kind of grams of helium were added to the cylinder if the volume was adjusted from 2.00L to 4.50L? (The temperature was hosted consistent.)
A helium balloon is filbrought about a volume of 5.60 L at 25 ∘C. What will the volume of the balloon end up being if it is put into liquid nitrogen to reduced the temperature of the helium to 77 K?0.046 L22 L1.4 L17 L3.7L
The best gas law describes the connection among the pressure P, volume V, variety of moles n, and absolute temperature Tof a perfect gas. Here is the connection expressed mathematically: PV=nRT wright here R is a proportionality constant. The systems of R are determined by the systems of push and volume used in the equation. When atm is offered for push and L for volume, the correct R value is 0.0821 L⋅atm/mol⋅K.How many air molecules are in a 14.0×12.0×10.0 ft room? Assume atmospheric press of 1.00 atm, a room temperature of 20.0 ∘C, and also ideal habits.Volume conversion:There are 28.2 liters in one cubic foot.
The Goodyear blimp includes 5.74×10^6 L of helium at 25 ∘C and 1.00 atm. What is the mass in grams of the helium inside the blimp? 2.34×10^5 g 2.80×10^6 g 1.12×10^7 g 9.39×10^5 g 2.30×10^7 g
What is the thickness of methane, CH4, in a vessel wbelow the pressure is 910 torr and also the temperature is 255 K? 0.057 g/L 16 g/L 0.92 g/L 697 g/L 0.72 g/L
