What does m mean in science?

Answer 1

In chemistry, as far as I know it usually stands for the mass, in g. Energy wise, still in chemistry, it standa for mass of the surroundings - similar things.

Answer 2

"M" is a symbol representing Molarity, which is mols per liter or mol/L (mols over liters). "M" also represents the concentration of a molecule, ion, or any such solution. It is changed when g's, L's, or other substances are added to the solution.

Answer 3

The capital letter M stands for molarity. It is the concentration of a compound in a solution. M stands for the units mol/dm^3. i.e. 0.02M = 0.02mol/dm^3= 0.02 mols of a compound in 1 dm^3 of water.

Answer 4

usuaully its meters, sometime miles (mi) also nice way of getting ppl to look at this question Tags: Maths [edit - please don't tag answers with non related terms. This is called spamming at best and is not good SEO practice]

Answer 5

The variable m is used to represent a variety of factors in science:

Lower-case (m):

• mass
• Magnetic quantum number
• molality

Upper-case (M/M):

• methionine
• as a unit for the molar concentration (molarity), equal to 1 mol/litre.
• molar mass (italicized M)

Answer 6

In chemistry a methyl group CH3 (1 carbon atom and 3 hydrogens) is often abbreviated to -Me. Most often when drawing the structure of a molecule.

Answer 7

meter, if you are measuring distance

Answer 8

Magnitude or mass
