1.5 because it is more!!!!!!!!!!!!!!!!!!!!!!!
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
Answer:
The answer to your question is P(chicken) = 0.30
Step-by-step explanation:
Data
number of pigs = 6
number of chickens = 7
number of cows = 10
P(chicken) = ?
Process
1.- Sum up all the number of animals
Total animals = 6 + 7 + 10
= 23
2.- Calculate the probability
P(chicken) = number of chicken / total number of animals
-Substitution
P(chicken) = 7/23
-Simplification
P(chicken) = 0.30
Answer:
the correct answer is 1.47 times 10 to the power of -3
