Why is molarity important in chemistry?

Answer 1

The molar volume equals 22.4 L and containing 6.02x10^23 (Avogadro's Number) molecular or atomic particles at standard temperature (273.15 K) and pressure (1 ATM), also knows as STP. This allows scientists to use the Ideal Gas Law of PV= nrt. Pressure (P), volume (V), moles (n), the radial gas law constant (r), and temperature. Using the molar volume and the Ideal Gas Law together allow them to determine how much space a certain number moles occupy dependent on temperature and pressure.

Answer 2

Molarity is the number of moles of solute in per liter of solution.

It is used to to tell you the quantity of a chemical that is dissolved in a solution.

Conversely, if you dissolve some chemical in a solution, then you can determine the molarity and know something about how many molecules you are adding if you know the molar mass of the chemical.

When designing or understanding a chemical reaction, it is much better to quantify the process in terms of the number of molecules involved in the reaction. Molarity is how you do that. Otherwise, describing chemical reactions and just measuring in grams of reagents gives no information of how much, in terms of number of molecules, are involved. That is why so much emphasis in chemistry is given to reaction balancing and molecular weight.

Answer 3

Molarity is important because it is the main measurement of concentration of solutions in chemistry. Molarity is measured as moles of solute per liter of solution.

Answer 4

Molarity is a measurement of concentration. The molarity of a solution tells a chemist how much of an element or compound is dissolved in a certain amount of the solution.
