You can't. There is no atmosphere in a vacuum.

What is Difference between vacuum condenser and atmospheric condenser?
An atmospheric condenser operates naturally at atmospheric pressure (1.013bar). A vacuum condenser operates at pressures below atmospheric and will use some sort of pump to provide a vacuum.
What gauge measures both vacuum and pressure?
Gauge pressure usually refers to the pressure difference between ambient, atmospheric pressure and the pressure in a vessel or line. A gauge pressure of zero would mean that the vessel or line was at atmospheric pressure. Normally the pressures of interest are ABOVE atmospheric so the gauge pressure is positive. Vacuum gauge pressure measures how far BELOW atmospheric pressure a vessel or line is. As such vacuum gauge pressure may be measured as a negative number - or for convenience it may be reported as a positive number with the caveat that it is "vacuum gauge pressure", meaning that the reported pressure is how far atmospheric pressure is above the pressure in the vessel or line.
How high is the atmosphreic pressure on the moon?
The atmospheric pressure on the moon is nearly zero (effectively vacuum).
What is absolute zero pressure?
absolute pressure is calculated from a vacuum (0 psi) and atmospheric pressure is14.7psia or 14.7 psi above a vacuum 1psi on a tire pressure gauge is called 1psig = 15.7psia 10psig=24.7psia 100psig=114.7psia etc.
Why collapse 1 gallon metal can with vacuum pump?
To demonstrate atmospheric pressure.
What is a total Vacuum?
A total vacuum is a space that is completely empty of matter. It is not practically possible to achieve a complete vacuum . An approximation to this is a space with pressure much less than atmospheric pressure.
What causes Back pressure on cooling system?
Condenser Backpressure is the difference between the Atmospheric Pressure and the Vacuum Reading of the Condenser, that is: Backpressure = Atm. Pressure - Condenser Vacuum Pressure Reading Usually, the condenser vacuum pressure is read by a manometer installed at the condenser. The atmospheric pressure is read using a barometer
Would you consider atmospheric pressure when finding the pressure of a liquid in a closed container?
pressure is usually measured relative to atmospheric this is called gauge pressure. if you compare against absolute zero pressure (vacuum) this is called absolute pressure.
How can you purify water without using heat?
Assuming that the gas law holds true, PV=nRT, you could purify salt water simply by reducing the atmospheric pressure by means of a vacuum. If you could somehow construct a vacuum and reduce the pressure, water will boil even at the lowest of temperatures. This can be seen in the city of Denver, where it is technically faster to boil water there than in Pittsburgh, just because its atmospheric pressure is less than 1 whereas in Pittsburgh, it would take longer to boil because its atmospheric pressure is about 1.Hope this Helps!
What is a vacuum distillation?
When pressure is reduced the boiling point will also reduce
How do you calculate the vacuum at a certain location if the atmospheric and absolute pressure is given?
It isn't clear what you want to calculate.
What is a vacuum and a partial vacuum?
Vacuum is measured in inHg or inches of mercury and a true vacuum is anything below zero on this scale...for reference normal atmospheric pressure or air pressure is about 14.7 inHg so anything less than that could be expressed as a vacuum or less than atmospheric pressure if above zero but less than 14.7 inHg...you can measure this with a vacuum gauge that you can get at any autoparts store but you can feel a vacuum as a suction just like your vacuum cleaner....So a vacuum is anyththing zero inHg or below and a partial vacuum is anything between zero and 14.7 inHg.
