Let us do some conversions first, then use the ideal gas law.
PV = nRT
1 Bar = 1.01325 atmospheres
80 Bar (1.01325 ATM/1 Bar) = 81.06 ATM
20 C = 293.15 K
new R = 0.08206 L*ATM/mol*K
(81.06 ATM)(100 L) = nI0.08206 L*ATM/mol*K)(293.15 K)
moles O2 = 337 moles O2 * 32 grams
= 10784 grams
about 24 pounds of oxygen

How do you calculate diameter of hydraulic cylinder to create ton pressure?
The equation Force = pressure x surface of the cylinder Electric power and torque and power you need to know what you want. After obtaining the surface area of ​​the circle diameter cylinder, the cylinder can get.
What temperature is the standard temperature used to measure solubility?
At STP(Standard Temperature and pressure), the temperature is zero degrees Celsius(273 Kelvin) and the pressure is 1 atmosphere. At RTP(Room temperature and pressure), the temperature is 25 degrees Celsius(298 Kelvin) and the pressure is 1 atmosphere.
What is the nature of p-v curve for air expansion in a pneumatic cylinder when the temperature is constant?
PV = RT is the ideal gas law P-pressure V-volume R-gas constant T-temperature then the equation becomes PV = constant therefore P = 1/V pressure becomes inversely proportional to the volume. hence as the volume increases the pressure decreases.
Is a hydraulic jack a hydraulic or pneumatic system?
Hydraulic , the jack uses fluid under pressure to raise the cylinder , releasing the pressure allows the cylinder to retract. Pneumatics is a similar concept using air pressure.

What happens to a gas heated in cylinder?
the gas expands and exerts more pressure on the sides of the cylinder. Basically, the pressure goes up due to a temperature increase.
A metal cylinder contains 1 mol of nitrogen gas what will happen to the pressure if another mole of gas is added to the cylinder but the temperature and volume do not change?
The pressure would double in size.
When charging a system with vapor refrigerant from a cylinder the cylinder will become?
Lighter, as the refrigerant is boiled off, and colder, as it has absorbed heat, and has a lesser pressure to reflect the current temperature / pressure relationship for the type of refrigerant
When a cylinder of oxygen is left standing in the sun the temperature of the gas reaches 42 and deg C. The cylinder has a volume of 10 liters and contains 8 moles of oxygen. What is the pressure atmos?
The pressure is 20,68 at.

As the pressure on a gas increases the volume of the gas decreases Whos law is that?
Boyle's law. In this law the condition is that the temperature of the gas is to be maintained constant.
