Answer:
The answer to your question is n = 0.838 moles
Explanation:
Data
Volume = 2.15 l
Pressure = 8.91 atm
Temperature = 5.81°C
moles = ?
Gas constant = 0.082 atm l / mol°K
Process
1.- Convert temperature to °K
Temperature = 5.81 + 273 = 278.81°K
2.- Write the Ideal gas formula
PV = nRT
-Solve for moles (n)
n = PV / RT
3.- Substitution
n = (8.91 x 2.15) / (0.082 x 278.81)
4.- Simplification
n = 19.16 / 22.86
5.- Result
n = 0.838 moles
