Pure acetylsalicylic acid has a melting point of 135.0 - 135.5 (degrees Celsius). What would you expect for the melting point is this was mixed as a 50:50 mixture with pure benzoic acid (melting point 121 - 122)? Explain.

Hmmm. 50:50 on mole basis or mass basis?
I'm assuming mass? I'm not sure.
The melting point would depress because the solution would be impure.
