Applying the relationship ,m = KH × p In the first case, 6.56 × 10-3 g = KH × 1 bar or, KH = 6.56 × 10-3 g bar -1 In the second case, 5.00 × 10-2 g = (6.56 × 10-3 g bar -1) × p or p = (5.00 × 10-2 g/6.56 × 10-3 g bar -1) = 7.62 bar

Q. The partial pressure of ethane over a saturated solution containing $6.56 \times 1 0^{- 3} g$ of ethane is 1 bar. If the solution contains $5.00 \times 1 0^{- 2} g$ of ethane, then what shall be the partial pressure of the gas?

$5$ bar

$10$ bar

Q. The partial pressure of ethane over a saturated solution containing 6.56×10−3g of ethane is 1 bar. If the solution contains 5.00×10−2g of ethane, then what shall be the partial pressure of the gas?

5 bar

10 bar

7.62 bar

3.72 bar

Applying the relationship ,m=KH​×p In the first case, 6.56×10−3g=KH​×1 bar or, KH​=6.56×10−3g bar −1 In the second case, 5.00×10−2g=(6.56×10−3g bar −1)×p or p=6.56×10−3gbar−15.00×10−2g​ =7.62bar
