S unit in chemistry

Key Terms. SI system: A series of units that is accepted and used throughout the scientific world. Of special interest to Chemistry is the mole, the base unit for expressing the quantity of matter. Although the number is not explicitly mentioned in the official definition, chemists define the mole as Avogadro’s number (approximately 6.02x10 23) of anything. S - Entropy s - seconds S - Sulfur s - solid s - spin quantum number SA - Salicylic Acid SA - Surface Area SAC - S-Allyl Cysteine SAC - Strong Acid Cation sal - salt (Latin) SAM - S-Adenosyl Methionine SAM - Spin Angular Momentum SAN - Styrene-AcryloNitrile SAP - Super Absorbant Polymer SAQ - Soluble AnthraQunone SAS - Small Angle Scattering The base units of length and volume are linked in the metric system. By definition, a liter is equal to the volume of a cube exactly 10 cm tall, 10 cm long, and 10 cm wide. Because the volume of this cube is 1000 cubic centimeters and a liter contains 1000 milliliters, 1 milliliter is equivalent to 1 cubic centimeter.

The International System of Units (SI) is system of units of measurements that is widely used all over the world. This modern form of the Metric system is based around the number 10 for convenience.

Strict adherence to SI units would require changing directions such as "add 250 mL of water to a 1-L beaker" to "add 0.00025 cubic meters of water to an 0.001-m 3 container." Because of this, a number of units that are not strictly acceptable under the SI convention are still in use. Some of these non-SI units are given below. We will use most of the fundamental units in chemistry. Initially, we will deal with three fundamental units.
