The concentration unit ppm is denoted as ( ), ppb is denoted as ( ), and ppt is denoted as ( ).
The concentration unit ppm is expressed as (one part per million), ppb as (one part per billion), and ppt as (one part per trillion).
Concentration units are expressed as ppm, which stands for (10 to the power of -6), ppb for (10 to the power of -9), and ppt for (10 to the power of -12).
The concentration unit ppm is expressed as (one part per million), ppb as (one part per billion), and ppt as (one part per trillion).
The concentration unit ppm is expressed as (one part per million), ppb as (one part per billion), and ppt as (one part per trillion).
A few parts per million, a few parts per billion, a few parts per trillion
The concentration unit ppm is expressed as (one part per million), ppb as (one part per billion), and ppt as (one part per trillion).
The concentration unit ppm is expressed as (ppm, part per million, one in a million), ppb is expressed as (ppb, part per billion, one in a billion), and ppt is expressed as (ppt, part per trillion, one in a trillion)
The concentration unit ppm is expressed as (one part in million), ppb as (one part in billion), and ppt as (one part in trillion).
Answer: One in a million, one in a billion, one in a trillion
