Given:
pH = 4.2 of tomato
Required:
hydrogen-ion concentration [H+]| for tomato juice
Solution:
The formula for the pH relating hydrogen ion concentration is pH =
-log[H+] where H+ is the hydrogen ion concentration. so, substitute the value
of pH
pH = -log[H+]
4 = - log[H+]
-4 = log[H+]
10^-4 = [H+]
[H+] = 1x10^-4M
Step-by-step explanation:
midpoint of BC is 63 middle of 60 and 65
0.468 divided by 6.5 is 0.072.
I'm not so sure about this answer, but i remember doing something similar to this. I think it's 3.
I am not sure if this is the only answer but i used trial and error to work this out.
I first calculated 6x 4= 24, meaning 4 hamburger. But that one left me with $8 left which would not work as each hot dog is $5 each. So the answer i got was:
4 hot dogs at $5 equals $20. 2 hamburgers equals $12. so all together, 20 plus 12= $32.
