Define Molefraction and Mass percentage. |
|
Answer» Solution :Mole &action is the ratio of the no. of moles o.f solute to the TOTAL no, of moles of all the components PRESENT in the solution. Molefraction of solute = `("No. of moles of solute")/("Total no.of moles of all the components ") ` `X_(A) = (n_(A))/(n_(A) + n_(B))` ` X_(B) = (n_(B))/(n_(A) + n_(B)) ` Mass Percentage : Mass Percentage is the mass of solute per 1000 g of solution. Mass percentage of solute `= ("Mass of solute")/("Mass of solution"). xx 100.` |
