A 250.0mL sample of oxygen gas was collected over water at a temperature of 25C and 750.0 nm Hg How many moles of oxygen gas were there in this sample if the vapor pressure of water at 25C is 23.8 mm?

PV=nRT (.855 atm)(.490L)=n(.0821)(306ºKel) .419=25.1n n=.0167 moles O2 .5344g O2 old answer by some slob: what the HELL. that makes no sence. well to an 11 year old. almost 12. =]

Is oxygen a solid or gas at room temperature?
For oxygen to be a liqud it has to be extremly cold and to be a liquid it has to be even colder. Room temp is quite hot. If you want more information have a look at wikipedia.
Why can ethyne be collected by water displacement?
Ethene is able to be collected over water because it is slightly soluble in water. The gas is made from ethanol vapor that is dehydrated by passing over a heated catalyst.
Under which conditions of temperature and pressure does oxygen gas behave least like an ideal gas?
Gases show least ideal behaviour at 1- high pressure and 2- low temperature.
How many grams are in a tank of oxygen?
Depends how big the tank is, the pressure in it, the temperature, etc.
What are the three elements that exist as a gas at room temperature and pressure?
Hydrogen, nitrogen, oxygen, fluorine, chlorine, and all the noble gases exist as a gas at standard temperature and pressure.
If oxygen gas is collected over water at temperature of 10C and pressure of 1.02 ATM and the volume of gas plus water vapor collected is 293 mL then what volume of oxygen at STP was collected?
fly
Is oxygen a solid or gas at room temperature?
For oxygen to be a liqud it has to be extremly cold and to be a liquid it has to be even colder. Room temp is quite hot. If you want more information have a look at wikipedia.
Equal volumes of nitrogen and oxygen at the same temperature and pressure would?
If equal volumes of nitrogen and oxygen are at the same temperature and pressure, then both (the nitrogen and oxygen) will contain the same number of particles
If the temperature is increased What happens to the partial pressure of oxygen in a sample of air?
In a sample of air, an increase in temperature will result in an increase in the partial pressure of oxygen.
Why is pressure and density important when giving the density of oxygen and nitrogen?
why is the temperature and the pressure important when giving the density of oxygen and nitrogen
Does oxygen has fixed volume?
no, no gas does, it depends on temperature and pressure.
Is oxygen free nitrogen pressure affected by temperature?
Assuming you are talking about oxygen gas and nitrogen gas the answer is yes. Each and every gas is affected by temperature.
Is oxygen an solid gas liquid?
Oxygen is a gas (in both forms: O2 and O3) at normal pressure and temperature.
How much is a oxygen tank?
Cost varies with size, pressure, and temperature requirements.
Why can ethyne be collected by water displacement?
Ethene is able to be collected over water because it is slightly soluble in water. The gas is made from ethanol vapor that is dehydrated by passing over a heated catalyst.
Under which conditions of temperature and pressure does oxygen gas behave least like an ideal gas?
Gases show least ideal behaviour at 1- high pressure and 2- low temperature.
A student is collecting the gas given off from a plant in bright sunlight at a temperature of 27 degrees celsius the gas being collected is probably?
oxygen
