1. What is the order of ppm, ppb, and ppt from smallest to largest?
The order from smallest to largest of ppm, ppb, and ppt is ppm < ppb < ppt.
Explanation:
Parts per Million (ppm), Parts per Billion (ppb), and Parts per Trillion (ppt) are units used to express very low concentrations of solutes in a solution. The order from smallest to largest is ppt < ppb < ppm. This means that Parts per Trillion is the smallest unit of concentration, followed by Parts per Billion, and finally Parts per Million.
These units are particularly useful when dealing with very small quantities of substances in solutions, especially in fields such as chemistry, environmental science, and industry. By using ppm, ppb, and ppt, scientists can accurately measure and communicate the concentration of solutes in a given solution.
It is important to understand the differences between ppm, ppb, and ppt, as they represent different magnitudes of concentration. For example, 1 ppm is equivalent to 1 milligram of solute per liter of solution, while 1 ppb is equivalent to 1 microgram of solute per liter of solution, and 1 ppt is equivalent to 1 nanogram of solute per liter of solution.
In conclusion, knowing the order of ppm, ppb, and ppt from smallest to largest helps in accurately understanding and interpreting concentrations in solutions. It is crucial for scientists and researchers to be familiar with these units to ensure precision in their work.
