प्रश्न
Write ideal gas equation for a mass of 7 g of nitrogen gas.
उत्तर
Ideal gas equation = PV = nRT
where, P = pressure, V = Volume, n = `"m"/"M"_"w"` = moles, R = gas constant, T = kelvin temperature, m = mass of gas and Mw = Molecular mass of the gas.
∴ Molecular mass of the nitrogen gas (N2) = 14.01 × 2 = 28.02
Here, n = `"mass of the gas"/"molar mass" = 7/28 = 1/4`
Therefore, the corresponding ideal gas equation is
PV = `1/4`RT
