Question

what is mole fraction​

Answer 1

Answer:

Mole Fraction

Explanation:

In chemistry, the mole fraction or molar fraction (xᵢ) is defined as unit of 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:.These expression is given below:- 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%).
