0.28 moles of nitrogen gas are there in 6.8 liters at room temperature and pressure (293 K and 100 kPa).
Ideal gas law :
An ideal gas is a gas in which atoms dose not exert any force on each other even after collision which walls and other atoms (inelastic collisions).
Mole definition:
The mole is the amount of compound present in a given system which has molecular mass as that of the mass of carbon12 .carbon 12
Using ideal gas law ,
PV=nRT
Given,
pressure = P = 100kPa
Volume = V = 6.8 Lit
Temperature = room temperature = T = 293 K
R= universal gas constant = 8.314
n= moles = ?
∴[tex]n = \frac{PV}{RT}[/tex]
∴ n = 100 × 6.8 / 8.314 × 293
∴n = 0.28 moles
