Answer: the reliability will be worse
Explanation:
Suppose we used 0.5 M NaOH to titrate our vinegar sample instead of 0.1 M.
Now by using 0.5M instead of 0.1M we are increasing the concentration of NaOH,
We know that the moles used = Volume x concnetration.
so for the same no of moles, if the concentration increases, the volume decreases.
Hence it will consume less NaOH.
now Since the volume decreases, the titration volume of less number will increase the % error.
Therefore the reliability will be worse.

ok follow me twitter dm me for answer The Kid D is my twitter
Explanation:
You have to find the gram formula mass of C6H6 then do mass (g) = mol x GFM
Thank you for the free 15 points .
Heptane means seven carbon atoms and since the general formula is CnH2n+2, heptane will be C7H16
