Hope you find this helpful if yes like me tag me as brainiest answer

friend your question seems incomplete it must be like this....

What is the mole fraction of KI in a solution made by dissolving 3.4 g of KI in 5.8 g of water?

And the answer is

Mole fraction=Mole of component÷Mole of all species in solution

Explanation

Solve in pic

Note that the mole fraction of water here must be necessarily 1−0.060=0.94.

Note that mole fractions, as they are here, are dimensionless quantities.
