Answer 1

Question:

A solution is made by mixing 250g hexane and 50g octanol . Mass percent of octanol is ??​

___________________________________________________________

Answer:

Mass percent of octanol: $\frac{Mass\:\:of\:\:octanol}{Total\:\:mass\:\:of\:\:the\:\:solution}$

Total mass of the solution = 250 + 50 = 300 g

Now, mass percent of octanol = $\frac{50}{300} \times100$ = 16.67%
