<span>Electrons, the negatively charged particles that carry electricity in metals, can be ejected from the material if it is bombarded by a large number of high-speed electrons. This effectively, leads to some metallic electrons being "knocked" out of the material. </span>

A closed container holds 2.0 moles of CO2 gas at STP. How many moles of oxygen can be placed in a container of the same size at

PilotLPTM [1.2K]

Answer: 2 moles

Explanation:

STP is Standard Temperature and Pressure. That means the pressure is 1.00 atm and the temperature is 273K. Since the oxygen is placed in the same container, we can use Ideal Gas Law to figure out what container the CO₂ used.

Ideal Gas Law: PV=nRT

P=1.00 atm

n=moles

R=0.08206 Latm/Kmol

T=273K

CO₂

$V=\frac{nRT}{P}$
