What amount (moles) of carbon dioxide gas is present in a compressed cylinder (900 mL) at 300 kPa at 25.0 C?

Using ideal gas law...in metric units, thanks.
786 torr = 104658 Pa
900 mL = 0.0009 m3
22 C = 295.15 K
R = 8.314 J/K-mol
PV = nRT
n = PV / RT = 104658 x 0.0009 / 8.314 x 295.15 = 0.0384 mol

n = moles = PV/RT = (300 kPa)(0.9 L)/(8.314 kPa-atm/deg-mole)(298 deg)
n = 0.11 moles CO2 present

What drives the movement of carbon dioxide from tissue into the bloodstream?
Movement of carbon dioxide is driffen by osmosis from and to the tissue and bloodstream. Also active transport can be used. Amount of CO2 present is monitored by means of the pH of your blood as dissolved CO2 is acidic.
What are the parts of the graduated cylinder?
There are little lines that you can read to find the amount of liquid in the cylinder.
What does brythomol blue tell you?
the amount of carbon dioxide
How do you increase the amount of carbon dioxide gas dissolved in soda?
Shake it
How does the burning of hydrocarbons release energy?
The carbon and hydrogen present in the fuel react with the oxygen that taken inside cylinder during induction and the explosion takes place.
How much pressure will compressed CO2 create when released in an air cylinder?
Whatever amount of pressure was used to compress the CO2 originally, can be reached (or nearly reached) when it is released into an air cylinder.
Why should the amount of carbon in the atmosphere today be reduced?
The present levels of carbon dioxide dioxide in the atmosphere are causing global warming and climate change.
Will you die if you inhale dry ice fumes?
Dry ice is solid form of carbon dioxide. Carbon dioxide will not kill you unless there is a sufficent amount present to replace the oxygen in the air around you. This will result in death by suffocation or asphyxiation.
Can cement be compressed?
Technically yes. Although the amount of change would be negligible. All matter can be compressed to varying degrees.Technically yes. Although the amount of change would be negligible. All matter can be compressed to varying degrees.
What is the amount of carbon in air?
There is no carbon in air but in the atmosphere there is 387 PPMV (parts per million by volume) present in the form of CO2 carbon dioxide.
What kinds of combustion fuel produce the greenhouse gas carbon dioxide?
Almost all fuels produce carbon dioxide when burnt, but only fossil fuels such as oil, coal and natural gas actually add to the amount of carbon dioxide naturally present in the atmosphere.
What would happen if layer of carbon dioxide around the earth got thicker?
There is no insulating LAYER of Carbon Dioxide round the Earth. The Carbon Dioxide is mixed up with the Oxygen and Nitrogen in Earth's atmosphere and is not present in the atmosphere as a layer. If the absolute amount of Carbon Dioxide in the atmosphere increases, the Earth would get warmer.
What causes a diesel to idle?
Diesels run on compressed fuel and air. An injector pump sprays fuel into the cylinder and mixes it with the air. When the piston rises to the top of the cylinder it compresses the fuel / air mixture and causes the mixture to ignite powering the engine. The speed of the engine is controled by the throttle plate which controls the amount of air entering the engine as well as the metering valve on the diesel pump which controls the amount of fuel that is sprayed into the cylinder.

What does a carbon footprint refer to?
The amount of carbon dioxide a person produces
Was carbon dioxide present in earth's early atmosphere?
Yes, carbon dioxide is present at varying concentrations at all levels of the atmosphere. Most of it is in the troposphere, the lowest level. It comprises about 0.04% of atmospheric gases, but this is a dynamic amount as it is constantly being removed and replaced by the processes of the carbon cycle.
Why is it dangerous to let air get into brake pipes?
Air is easily compressed and the amount of fluid that must be pushed into the brake lines to transmit the force to the brakes increases greatly when air is present. Normally, the brake is activated by the brake pedal connected to the master cylinder. The master cylinder has a small piston that moves when you press on the brake pedal and that piston pushes brake fluid out of the cylinder and into the brake lines which ultimately causes brake fluid to flow to the wheel cylinders which them move and provide the force to press the brake pad against the disc or brake drum connected to the wheel. When there is air in the brake lines, the master cylinder pushed more fluid in than the amount of fluid that comes out at the wheel cylinders. This is because the air in the brake line is being compressed where in the normal situation there is essentially no compression of the brake fluid. Thus, to apply the same amount of force to the brake pads, the piston in the master cylinder has to move further. If there is a lot of air, then the piston has to move much further. If there is truly a large amount of air, then the piston in the master cylinder may move through its entire allowed distance and still not provide enough pressure to adequately press the brake pad against the frictional surface connected to the wheel. Three things to notice that decrease braking effectiveness and hence are dangerous. 1. Air in the lines gets compressed so that the amount of force creating friction at the wheels is less when compared to the same amount of mechanical movement of the brake mechanism. 2. The maximum amount of braking force is limited if the amount of air allows the piston in the master cylinder to travel its full length. 3. If you have air in the lines, it may be caused by a leak and more air may enter and further decrease braking effectiveness. Air in brake lines is usually a simple problem and easy to correct by "bleeding" the brakes.
