In this video we go over how to calculate the mole fraction of any given component of a solution. For these, we use the formula: Xa = na/ntotal.
Some of the common questions types are: "__ moles of solute is dissolved in __g of water. What is the mole fraction of the solute", "__g of water is mixed with __g of solute. What is the mole fraction for each substance", and finally the problems with multiple solutes with percent masses which you need to convert to moles to get each corresponding mole fraction.
Hope this helps someone! Let me know down below if:
- you have an easier way to do these
- you found a mistake or want clarification on something
- you found this helpful :D
* I am not an expert in this topic. I am just a clinical lab scientist and life-long student who learns best from videos/visual representations and demonstration and have often turned to RU-vid for help learning. My hope is that others in the same boat find and benefit from this.
