A sample of a salt and water solution is homogeneous throughout. Is this sample a mixture or a pure substance? A. A mixture, because it can have a variable composition B. A pure substance, because it has a definite composition C. A mixture, because it has a fixed, definite composition

A...
Wouldn't it be C since the mixture is homogenous?
mixture can be homogeneous or non homogeneous........but it doesnt meam it is pure substance...in pure substance every atom/ molecule in it is same....u cant differentiate betn them...eg in the pure salt every molecule is NaCl but in mixture u can differentiate betn them eg in salt water mixture u can differentiate bet molecule of salt NaCl and molecule of water H20.....
Then it wouldn't be called a mixture...In my opinion. I believe it's C because a homogenous mixture has the same composition, or density, of molecules everywhere.
As in the salt isn't concentrated in one spot, but equally dissolved.
You're basically explaining that all mixtures are heterogenous.
