How is the concentration of a solution measured?

V is the volume of solution, n is the number of moles, and C is the concentration.

Thus, you must first understand what is included in the solution. To illustrate, let's use HCl:

The first step is to calculate the number of moles, which is equal to the mass in grams divided by the molar mass of HCl, in this case 36.45g/mole (1g/mole is hydrogen and 35.45g/mole is Cl). Let's say you have 5g of HCl in a 500ml solution.

After obtaining the answer, divide it by the volume in liters, or 0.5L.

The unit of measurement for your response is mol/L, sometimes abbreviated as simply M.

Should receive 0.27 mol/L as the response for this example.

I hope I was of assistance.

The concentration of a solution is measured in terms of mass/volume, moles/volume, or percent by mass/volume. Common units include grams per liter (g/L), moles per liter (mol/L), or percentage (%).
