Concentration Units

Subject: Chemistry

Book: General Chemistry

Chemists use various units to express solution concentration, including molarity (mol of solute / L of solution), molality (mol of solute / kg of solvent), percent by mass or volume, and parts per million (ppm). Each unit is suited for different applications: molarity is common in laboratories, while molality is preferred in boiling point elevation or freezing point depression calculations. Proper unit selection ensures accurate and consistent results.
