Question 1

What is molarity?

Accepted Answer

Molarity (M) is the number of moles of solute per liter of solution. 1 M = 1 mol/L. It tells you how concentrated a solution is.

Question 2

How do you prepare a 1 M solution?

Accepted Answer

Dissolve 1 mole of the solute in enough solvent to make exactly 1 liter of solution. For NaCl (M=58.44), that means 58.44g in 1 L.
