It is correct, next time re-check your answer and don't second guess yourself. ;3
Heptane means seven carbon atoms and since the general formula is CnH2n+2, heptane will be C7H16

Answer:
The pH of the sample is 3,4.
Explanation:
We calculate the pOH from the formula pOH = -log (OH-). We know that for all aqueous solutions: pH + pOH = 14, and from there we clear pH:
pOH= -log (OH-)=10,60
pH + pOH = 14
pH + 10,60 = 14
pH=14 -10,60
<em>pH=3,4</em>
