In chemistry, the mole fraction or molar fraction (xᵢ) is defined as the amount of a constituent (expressed in moles), nᵢ divided by the total amount of all constituents in a mixture (also expressed in moles), nₜₒₜ: xᵢ=nᵢ/nₜₒₜ The sum of all the mole fractions is equal to 1: ∑ᵢ₌₁ᴺnᵢ=nₜₒₜ; ∑ᵢ₌₁ᴺxᵢ=1 The same concept expressed with a denominator of 100 is the mole percent or molar percentage or molar proportion (mol%).
