= Density of acetic acid = 
= Mass of acetic acid = 
= Volume
Density is given by
The volume of acetic acid is .
Answer:
The answer is "true"
Explanation:
ANP, or ANF, is a human peptide hormone, that controls your blood pressure, a cardiac atrium secretion hormone. It response primarily to the volume and stress expansion of the auricles and ventricles.
- ANP's main function decreases the amount of increased extracellular fluid by increasing renal excretion.
- This hormone is primarily developed by cardiovascular myocytes and, emanates from the wall tension locally, that's why the given statement is true.

The motion becomes smaller. Lets tale the example of water. At gaseous state, the particles moves rapidly in all directions. As it is cooled, it becomes liquid and the motion becomes smaller because the particles are now closer to each other as the attraction forces becomes stronger. As it is cooled further, it becomes solid. At solid state, the particles now vibrate in fixed position. Apply this concept to motion of molecules in a substance.
