Answer:
The mass of water to be added is 2 pounds
Explanation:
The given parameters are;
The mass of the given solution = 2 pounds
The concentration of the given solution = 30%
The desired concentration of the solution = 15%
The mass, m of the acetic acid in the given solution = 30% × 2 pounds
m = 30/100 × 2 pounds = 0.6 pounds
To make a 15% acetic acid solution of acetic acid, the mass X of the required volume, is given as follows;
15% of X = 0.6 pounds
15/100 × X = 3/20 × 0.6 pounds
∴ The mass of the solution required X = 0.6 × 20/3 = 4 pounds
The mass of the solution that will contain 0.6 pounds of acetic acid giving a 15% acetic acid solution is 4 pounds
Therefore, the mass of water to be added to the original solution to make the a 15% acetic acid solution is 2 pounds.
Answer: Option C
Explanation:
Chylomicron is a small fat globule which is made of protein and lipids. These substances are found in the lymphatic fluid and blood where they tend to transport fat from the entry in the intestine to the liver and adipose tissue.
Once, one eats the fatty meal the blood is full of a number of chylomicrons which provides the blood texture.
The food that is digested is absorbed and transported to various parts of the body.
