I had a general inquiry about a relation in my physical chemistry textbook. It stated that when determining the partial pressure of an ideal gas component in a mixture/solution, instead of using the standard Dalton's law: P_{i}= x_{i}P_{tot}, one can simply use the relation P_{i}= (volume i : volume mixture or solution)P_{tot}.

I am having a hard time convincing myself of this and have not been able to find a derivation of this in either my book or online. Can someone please help me get started?

2. Relevant equations

3. The attempt at a solution
