Calculate the total pressure in a mixture of 8 g of dioxygen and 4 g o

1.	Calculate the total pressure in a mixture of 8 g of dioxygen and 4 g of dihydrogen confined in a vessel of 1dm^(3) at 27^(@)C. R =0.083 bar dm^(3)K^(-1)mol^(-1).
Answer» SOLUTION :Total NUMBER of moles present in the MIXTURE `=8/32 + 4/2 = 2.25` (Mol. mass of `O_2 = 32, " Mol. mass of " H_2 = 2`) According to the gas equation, `PV = NRT` or `P xx 1= 2.25 xx 0.083 xx 300` or `P= 2.25 xx 0.083 xx 300 = 56.025` bar
