माना कि गैस मिश्रण `H_(2)` तथा`O_(2)` के आंशिक दाब क्रमशः `P_(1)` तथा` P_(2)` है ।
` H_(2)` गैस के लिए- ` P_(1) V_(1) = P_(2)V_(2)`
` 0.8 xx 0.5 = P_(1) xx 1 `
या ` P_(1) = ( 0.8 xx 0.5)/1 = 0.4 " bar "`
` O_(2) ` गैस के लिए -
` 0.7 xx 2.0 = P_(2) xx 1 `
` P_(2) = ( 0.7 xx 2.0 )/1 = 1.4 " bar"`
अतः गैस मिश्रण का कुल दाब ,
` P = 0.4 + 1.4 = 1.8 " bar "`
