3.41 is  the pH value of a sample that has ten times fewer hydronium ions than an equal volume of a vinegar sample with a pH value of 2.4.

Explanation:

pH of the first sample of acetic acid = 2.4

to know the [H+] concentration in the acetic acid solution, the equation used is:

pH = -log [H+]

[H+] = 10^{-pH}

[H+] = 10^{-2.4}

[H+]  = 3.98 X 10^{-3} M

The concentration of H+ ion in first case is 3.98 X 10^{-3} M, the second sample has ten times less hydronium ion so concentration of first case is divided by 10.

3.98 x 10^{-4} M

Now pH of the sample having 10 times fewer ions of acetic acid:

pH = -log [H+]

putting the values in the above equation:

pH = -log [3.98 x 10^{-4} M]

pH = 3.41

If solution has ten times less hydronium ion the pH will change to 3.41.

poizon [28]

We are given the following equation:

y = y0 e^-0.0001216 t

where y = 1/5 y0, y0 is the original amount

So solving for time t:

1/5 y0= y0 e^-0.0001216 t

t = 13,235.51 years

 

So the human died about 13235.5 years ago
