Question

Calculate total pressure of mixture containing 8gm dioxygen and 14 gm dinitrogen in 2lit container at 270K ?​

Answer 1

Answer:Answer

Given,

Mass of oxygen  = 8 g, molar mass of oxygen = 32 g/mol

Mass of hydrogen = 4 g, molar mass of hydrogen = 2 g/mol

Therefore amount of oxygen = 8/ 32 = 0.25 mol

And amount of hydrogen = 4/2 = 2 mol

From the gas equation PV = n RT, we get,

P X 1  = (0.25 + 2)  X 0.083 X 300 = 56.02 bar

Hence, the total pressure of the mixture is 56.02 bar.
