Answer:
The answer to your question is P = 1.95 atm
Step-by-step explanation:
Data
Pressure = P = ?
number of moles = n = 0.122
Volume = V = 1.5 l
Temperature = T = 20°C
Constant of ideal gases = 0.082 atm l/mol°K
Process
1.- Convert temperature to °K
T = 20 + 273
T = 293°K
2.- Write the formula of ideal gases
PV = nRT
-Solve for P
P = nRT/V
3.- Substitution
P = (0.122 x 0.082 x 293) / 1.5
4.- Simplification
P = 2.93 / 1.5
5.- Result
P = 1.95 atm
