Question

A solution contain 2.5 mole of ethanol and 7.5 mole of h2o calculate mole fraction of each compound of solution

Answer 1

Answer:

mole fraction of C2H5OH is 0.25

mole fraction of H2O is 0.75

Explanation:

we given the no of moles of each so we can calculrate the total no moles and mole fraction of each by using the formula

mole fraction of substance=no of moles of that substance in a soln /total no moles of soln i.e (no of moles of solute +no of moles of solvant).
