Answer:
The correct option is;
pH = 4.1
Step-by-step explanation:
The given information are;
The hydrogen ion [H⁺] concentration in tomato juice = ![10 ^{-4.1}](https://tex.z-dn.net/?f=10%20%5E%7B-4.1%7D)
The pH of a solution = -㏒{H⁺] = -㏒(
) = -(-4.1) × ㏒(10) = 4.1
The pH of the of the tomato juice = 4.1
The pH is the term used to refer to the acidity of water with the range of pH values ranging from 0 to 14 where pH values of a solution lesser than 7 are considered acidic while pH values above 7 indicate a basic solution.
Answer:
$0.0756 for 18 oz
$0.0634 for 32 oz
Step-by-step explanation:
Find the area of the rug by multiplying the length by the width:
7 x 5 = 35 square meters.
Now multiply the area of the rug by the cost:
35 square meters x 285 pesos per square meter = 9,975 total pesos.
![\it 3x+2y=14 \\ 5x-2y=18 \\ ------\\ 8x \ \ \ \ \ \ \ =32 \Rightarrow x = 32:8\Rightarrow x=4 \ \ \ (*)](https://tex.z-dn.net/?f=%5Cit%203x%2B2y%3D14%0A%5C%5C%0A5x-2y%3D18%0A%5C%5C%0A------%5C%5C%0A8x%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%20%3D32%20%5CRightarrow%20x%20%3D%2032%3A8%5CRightarrow%20x%3D4%20%5C%20%5C%20%5C%20%28%2A%29)
