`5.5mg` of nitrogen gas dissolves in 180g of water at 273 K and 1 atm pressure due to nitrogen gas. The mole fraction of nitrogen in 180g of water at 5 atm nitrogen pressure is approximatelyA. `1xx10^(-6)`B. `1xx10^(-5)`C. `1xx10^(-3)`D. `1xx10^(-4)` |

Answer» Correct Answer - B Amount of nitrogen gas at 5 atm `=5xx5.5=27.5mg` `=27.5xx10^(-3)g` `"Mole fraction of "N_(2)=("Moles of "N_(2))/("Moles of "H_(2)O+"Moles of "N_(2))` `("Moles of "N_(2))/("Moles of "H_(2)O)" "(becauseN_(2)lt ltH_(2)O)` `=((27.5xx10^(-3))/(28))/(180/(18))=1xx10^(-5)` |
