Solutions are homogeneous mixtures. Solutions consist of solutes and solvents (the more voluminous substance into which the solute dissolves). Solution concentration measures the amount of solute per liter of the solvent. Molarity is a commonly used measure of solution concentration.
Pure acetic acid (HC2H3O2), also known as glacier acetic acid, is a liquid with density 1.049 g/mL at 25oC. Calculate the molarity of a solution of acetic acid made by dissolving 20 mL of glacier acetic acid at 25oC in enough water to make 250 mL.
S7P1A15 (containership - mass).
Pj Problem of Interest is of type containership (mass).
Mass of 20 mL of HC2H3O2 = 1.049 x 20 = 20.98 g
Molar mass of HC2H3O2 = 24 + 4 + 32 = 60 g
So, mol in 20 mL of HC2H3O2 = 20.98/60 = 0.3496 mol.
0.3496 mol in 0.250 L
So, 0.3496/0.250 = 1.398 moles in 1 L = 1.398 M.
The point . is a mathematical abstraction. It has negligible size and a great sense of position. Consequently, it is front and center in abstract existential reasoning.

The Universe is composed of matter and radiant energy. Matter is any kind of mass-energy that moves with velocities less than the velocity of light. Radiant energy is any kind of mass-energy that moves with the velocity of light.
