Answer: 0.24 moles
Explanation: Using IDEAL GAS LAW
PV=nRT
where,
P = pressure of the gas= 2.0 atm
V = volume of the gas= 3.00L
T =Temperature of gas=25^0C=(25+273)K=298K
n = number of moles of gas=?
R = Gas constant = 0.0821 Latm/moleK
n=\frac {PV}{RT}=\frac {2.0\times 3.0}{0.0821\times 298}=0.24moles
A plasma is a hot ionized gas consisting of approximately equal numbers of positively charged ions and negatively charged electrons. The characteristics of plasmas are significantly different from those of ordinary neutral gases so that plasmas are considered a distinct "fourth state of matter
