Define Molefraction and Mass percentage.

Explanation

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.`
