Im pretty sure it weight because when we are on different plants with a different amount of gravitational pull our weight changes
hope this helps :)
Answer:
Explanation:
pH = − log [H+] , we can solve for [H+] as,
− pH = log [H+] ,
[H+] = 10^−pH,
so PH =2.4 in you case is
[H+] = 10^-2.4 =0.00398
The option are not correct it looks
I would say the answer is C
hope this helps :)
