Answer:
2.99 mol
Explanation:
Number of moles of CO₂ = ?
Volume = 67 L
Temperature and pressure = standard
Solution:
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
By putting values,
1 atm × 67 L = n ×0.0821 atm.L/ mol.K × 273.15 K
67 atm.L = n×22.43 atm.L/ mol
n = 67 atm.L/22.43 atm.L/ mol
n = 2.99 mol
